Publishing a .m matlab file to pdf: display latex is blurred / poor quality - matlab

I'm using the command publish('myFile.m', 'pdf') within the Matlab gui. The resulting file is crisp and perfect except for any of the LaTex within it which is blurred almost to the point of not being readable. Where do you think the source of this issue is? Are there any workarounds?
Context: I'm using Matlab 2014a on a macbook pro retina. Problem persists for all other generation: issue is with the .png
Note: The whole GUI was completely blurred on install. I have since updated the version of java being used by Matlab using this solution:
cd /Applications/MATLAB_R2013b.app/sys/java/jre/maci64
mv jre jre.orig
ln -s /Library/Java/JavaVirtualMachines/jdk{jdk.version}.jdk/Contents/Home/jre

Answer from Matlab Support
Hello James,
I am writing in reference to your Technical Support Case #01107596
regarding 'LaTex rendering in very low quality when publishing'.
I apologize for the inconvenience you experience. Unfortunately what
you observe is a bug in the way that "publish" renders LaTeX equations
when publishing to .pdf. At the moment there is no direct work-around
for it.
The best indirect work-around is to publish to LaTeX instead of .pdf
and then compile the resulting TeX file using a LaTeX compiler. I
appreciate that this work-flow is sub-optimal. The relevant
development team is already notified about it.
I hope this e-mail clarifies the issue you experience. Once again I am
really sorry for this inconvenience. I will now close this service
request as having a bug report submitted but I will reopen it if you
require further clarifications. Do not hesitate to contact us again if
you have a new query regarding MATLAB's functionality.
Please preserve the Reference ID below in further correspondence on
this query. This allows our systems to automatically associate your

transparent background in figure (matlab)

I'd like to save a matlab figure with transparent background, on mac, and import into Keynote.
This question was asked in 2013, but I understand matlab has changed its graphics handling since then. Is there a 'good' way to do this? The plotting syntax is so scattered and overloaded.
I looked for this myself some time ago. Mathworks seems to state that this is not directly possible in matlab and that it isn't a feature they plan on introducing as well:
http://ch.mathworks.com/matlabcentral/answers/19907-transparent-background-for-figures
But as stated in the link it can easily be achieved using a third-party program (for example inkscape, which is freeware(opensource?) program) if you export the figure as a .eps or .pdf. This basically enables you to directly edit or delete certain parts of the image.
This is probably not exactly what you were looking for, but I know of no easier native solution than this. However the author refers to export_fig which might directly solve you porblem (I don't have any experience using it, sorry).

How to implement fixed point operations without Fixed Point Designer Library in Matlab?

I am supposed to work with an existing code in my work and at some places the previous programmer has extensively used Fimath function. Unfortunately, I am not having the license for the Fixed Point Designer toolbox and was looking for some alternatives.
I tried getting the fimath.m file from another source but it is referencing to some embedded libraries in the toolbox.
Is there some other way in which I can bypass this problem?
Thank You

Installing a Matlab App in MATLAB R2012a

First off I'm not a regular Matlab user, so this might appear as a rather simple question, but how do you install Apps in Matlab R2012a? Is it even possible? I found a link for how to do it in R2012b here, but I can't find any guidelines on how to do it in R2012a.
I have a custom app that was sent to me by a colleague at another research institution, and I think they must have a more recent version of Matlab that us. His instructions were to go to the Apps tab in the tool bar and select Install Apps, but in R2012a, I can only see File, Edit, Debug, Parrallel, Desktop, Window and Help. I've also had a look in the Product Help guide in Matlab, but I couldn't find a relevant entry.
Any help would be greatly appreciated.
I believe MATLAB apps were introduced in R2012b, and that it's not possible to install or use them in earlier releases. You would need to contact your colleague, and ask them to supply an unpackaged version of the application (i.e. just the code).

Where can I find good open source code flow visualization software?

I am working on an academic research regarding some very long functions in the Linux kernel (link, link).
For that research, I would like to use some code flow visualization tool, that would be able to plot a graph in which each vertex is a decision point and each edge is a piece of code which runs in a consequent way.
Do you know of any good, open source project that can visualize C code?
Perhaps a tool like KCacheGrind would be of help. It generates call graphs based on actual calls and cannot pre-generate a call graph without actually running the program, which may not suit your needs, but then it again it may.
History flow's are very neat for changes/diff across multiple versions.
Codeplex has a project, Dependency Visualizer which does support C also.
Gprof2Dot can render oprofile, this would get you dynamic info also.
CodeViz also (static tool) would work.
If your using gcc, gcc-xml has an introspector plugin also todo this.
You appears to want to acquire a flowchart of C source code ("decisions", "code blocks").
Something like this C flowchart?
To do this correctly, esp. for Linux kernal code, I'd expect you to have to preprocess the code first to get rid of macros and conditionals. I would assume that GCC would construct such a graph internally and that you ought to be able to get your hands on that graph.
Doxygen does some amount of 'visualization',
but you need to work on the code a bit for it to be usable.
Another interesting thing to check would be lxr
Linux Cross Referencer is a software toolset for indexing and presenting source code repositories. LXR was initially targeted at the Linux source code, but has proved usable for a wide range of software projects. lxr.linux.no is currently running an experimental fork of the LXR software.
I can recommend Sourcetrail. Can work with a compile_commands.json. Not sure if it's still maintained, though. But it's foss and you can fork it!

As a developer I really don't like writing documentation but when I have to I'd like to make the process as painless as possible.
The problem with Word is that it constantly gets in my way. I worry more about the layout than about the actual content ... that's why I'd like to get rid of Word.
Ideally I'd like to write my content and then 'compile' it into a document.
I've heard of LaTeX but I don't have any experience with it whatsoever. Would this be the right technology for the job? What editor (Windows) should I use? Is it a good idea to start with LyX?
EDIT: I'm not asking about documenting code (I use Sandcastle for that).
Update 2014:
We have now switched to GFM (GitHub Flavored Markdown).
It's really easy to work with.
Write code & documentation in the same IDE!
Everything can be versioned!
Get great output either as raw txt, html or pdf!
My solution to this was to invest some time in creating a decent Word Template for myself.
The important thing to do is make sure you have a Style defined for everything you can put in the document.
Once you have all the Styles defined and all of the document content tagged with the correct Style instead of formatted in an ad hoc fashion, you'll be surprised how easy it is to produce good looking Word documents quickly every time.
The wider problem here is that everyone spends hours in Word and yet it is very rare for companies to invest in Word training. At some point you have to bite the bullet and take the time to teach yourself how to use it properly, just like you would with any other tool.
Anything you can do with LyX you can do with LaTeX. LaTeX is suitable for all sorts of things; it has been used for everything from manuals to lecture slides to novels.
I think LaTeX is probably worth looking into as an option; if you've ever wanted to "code" for your word processor, LaTeX is for you. At the simplest level you can define new commands to do things for you, but there's a lot of power there. And the output looks really neat.
In my opinion, LyX is fantastic in certain circumstances, handy in others, and occasionally just gets in your way. I think it should be seen as a productivity booster for LaTeX. In other words, learn to use LaTeX before trying LyX. Both are of course free and available for Windows, though the learning curve is quite steep compared with MS Word. For long documents, or plenty of similar documents, LaTeX/LyX is probably a worthwhile investment.
I've found that wikis can be good for this. Find a wiki you like that lets you do a bit of formatting, but nothing really heavy. Ideally it should let you format code easily too - to be honest, the markdown available on SO is probably a good start.
That way:
You have change tracking built-in (assuming a decent wiki)
You can edit from anywhere
Everyone always sees the same documentation (instant distribution)
You can concentrate on content instead of formatting
You could write your documentation using your own XML format and then transform it into any format with XSL (e.g. PDF via FOP+XSL-FO ).
See also the DocBook XML format.
LaTeX is an extremely powerful tool and might well be overkill here as it is designed for scientific/mathematical literature. It has a (relatively) steep learning curve and can be tricky to coax to do exactly as you want if you're new to it. I LOVE LaTeX, but it is not really a general purpose word processor.
Have you considered OpenOffice instead?
LaTeX is really a very powerful language if you need to write documents.
Perhaps you can try texmaker, a cross-platform LaTeX editor:
Texmaker is a clean, highly
configurable LaTeX editor with good
hot key support and extensive Latex
documentation. Texmaker integrates
many tools needed to develop
documents with LaTeX, in just one
application. It has some nice
features such as syntax highlighting,
insertion of 370 mathematical symbols
with only one click, and "structure
view" of the document for easier
navigation.
What about using HTML? This way you could then publish the documentation if there will be need for many people to access it from many places.
Despite all efforts and reasonable expectation I don't think Word Processing has been "solved" yet.
My response to what I also personally find a deeply frustrating experience with MS Word is to avoid it altogether and use an auto-documenting tool like GhostDoc to generate XML from what I've already written in the code (DRY!) and deal with the XML from an XSLT based intranet site or similar later.
Are you talking about documenting your actual code? If so, I recommend Doxygen for unmanaged code and Sandcastle for managed code. Both will compile your help or build it as a website for you.
Both applications will read special tags above functions / classes / variables and compile that into the help.
Well I've never found anything wrong with MS-Word in the first place. (i.e if you take the time to know how to use it effectively). OpenOffice indeed is an amazing & credible free alternative - but then if you hate MS Word for layout related problems, the same problem is gonna occur with OpenOffice too.
Never tried the Latex system myself, but have heard its good for scientific work. I think using some HTML WYSIWYG editor would be best for you, if you want to just focus on the content.
I considered a wiki, but I decided to go with a modified Markdown notation, for the simple reason, that a wiki's content isn't easily exported and distributed outside of the wiki itself, while the Markdown can be rendered into HTML.
Answer to chris' question about my workflow: I write the documentation with a Notepad-like application (TextWrangler, only because of its word-wrapping feature) in its raw Markdown format. Then I have a small localhost documentation website with my modified Markdown parser (extended for a few features and a bit more HTML-oriented functionality) that checks for the timestamps for the documentation files - if a file has been updated, it parses that file into HTML, and stores the file in a cache.
This way I'm able to edit the source documentation on my desktop, and just press F5 in my browser to see the results immediately.
I haven't got around to trying it yet, but I've always thought AsciiDoc would be good for this kind of thing.
If you want something simpler than LaTeX, you can have a look at ReStructured Text
Read this book: http://en.wikipedia.org/wiki/The_Pragmatic_Programmer . There is some idee fixe inside, so that documentation should be built automatically. Think about using your IDE for this, or look for some additional tools. Most modern languages support generating documentation as you write the code. This can simply maintain your doc in touch with latest changes in the code.
I prefer to use a RTF editor which is a lot less clunkier than words. This way the formatting and all the headers/footers nonsense will not take up half your time. Wordpad has worked for me on several occasions. I'm stuck with Word for now though :(
there are a lot of possible ways:
embedded documentation, e.g. javadoc: good for describing APIs, not so good for the "big picture"
plain html: can be checked in under version control, a definite plus
a wiki, e.g. confluence -- great for collaboration, but has version control different from your source
LaTeX or somesuch: better suited for books or papers than typical documentation; support for graphics is cumbersome
an Office clone, e.g. OpenOffice: mostly the same as Word+Visio, but open source, with a nicer document format
I usually document the software structure (the "metaphors" of a project, component interrelations, external systems) up front, using Visio, in "freeform" UML. These are then embedded in confluence, which can be converted to PDF if someone wants a printout.
LyX
LyX is a WYSIWYM front end to LaTeX: You get the convenience of a document processor (somewhat similar to Word) with the consistency and power of LaTeX: It doesn't get in your way and can do a lot of things that professional writers need.
Note: The correct answer for you really depends on your way of thinking --- we can't decide this for you. This answer simply shows an excellent choice if you think of documentations as documents and want something similar to Word (where Word is good) that doesn't suck as Word (where Word is bad for programmers).
But many programmers think of documentation differently and hence prefer different metaphors. I myself had the same problem years ago, worked with LaTeX (as I am a mathematician), found LyX and finally settled on a Wiki/Source system that I wrote myself.
Vim is the solution for anything that means writing plain text in the most efficient possible way. If you need formatting, then use XML, Latex or something similar (in Vim).
Vim changed my life!
Simple answer: LaTeX sounds like just what you are looking for.
I use it for writing documentation myself. I will never go back to Word if I have the option.
At phc, we started with latex, then moved to docbook, and have settled (permanently I hope) on Restructured Text/Sphinx.
Latex was chosen because we are academics, and latex is the tool of choice. I believe it didn't generate good enough HTML.
Docbook was chosen for power, but it was very unwieldy. It put us off writing any documentation: code had to be manually formatted, we kept forgetting the syntax, and it was difficult to read. The learning curve was also steep.
Finally, we moved to reST, using sphinx, and that was a great decision. Documentation is now very easy to write, and both PDF and HTML versions look beautiful (though the PDF could do with some customization). Its very easy to customize too.
The best bit about reST though, is that its human readable in source form. That is a wonderful advantage. I've switched to using reST for all my stuff now, especially anything over the web (except of course academic papers, where one would be foolish to use anything but latex).
You may want to look into doxygen at http://www.doxygen.nl/, see their nice examples. In this case, the documentation is presented by tags in comments in the source.
Another option would be to use an online system like trac from http://trac.edgewall.org/ which is a wiki/doc/issuetracking system that lives on top of subversion.
