I ran a code with various functions. But the output was not complete and it showed error 'Text scatter requires Text Analytics Toolbox'. I think I have installed the complete MATLAB. Can anyone please tell me why do this error occur and how to solve it?
You don't have a "complete" MATLAB, there are multiple toolboxes available with extend the functionality of MATLAB. An overview is given here: https://mathworks.com/products.html
When you log in with your mathworks account and go to https://mathworks.com/mwaccount/ you can see the products connected to your license.
I guess if you want to use that function, you have to buy it. Alternatively you can also look around for a substitute.

I have searched a lot and tried several approaches. I believe I am doing something wrong as I am unable to have code from gist in the medium plataform bloggers.
I have only get the links on there but the code does not show or is not integrate. I have tried all the modalities of gist share code possible and paste using the embedded option in medium.
For example,
https://gist.github.com/GMoneyAccount/84fb1a9836aa91054e1714ac9d176630

This code does not show in the medium.
What I am missing? I have looked how people do but does not work for me for some reason and also I have changed from google to firefox and nothing changed.
The vendor that they use for processing embeds is currently down. You can watch the status of the incident here: http://status.embed.ly/
So, basically, the way you are doing it isn't a problem. You'll just have to wait until the incident resolves.
Cheers.
I'm working with a PLC program that runs over a hundred subroutines in parallel, and each one affects the flow of the others. Countless labels and GOTOs, function calls, etc. My office desk is covered with little stickynotes to help me visualize and track the flow through the program, but it's starting to get too complex to manage that way. Has anyone ever heard of any sort of graphical flowchart-ish program to help organize stuff like that? What I'm picturing is a little text box that I can fill full of pseudocode, then link to other textboxes. Unless I'm actually working in them, the boxes stay collapsed, and you only see a title or something to show what it is. All the links connected to my "open" box are red, or bold, and all other links are dim gray, or maybe not even shown.
Does anything like this exist? I've heard that MATLAB uses something similar to what I'm picturing, but what I want is just a generic sort of "fill in your own info" program; not language-specific. I'd be tempted to make one on my own, but I'm way too busy with WORK-work to start creating NOT-AT-WORK-work for myself.
You can try Dia or yEd. Both are available for linux, I know that yEd is also for Windows. Those are diagramming tools, maybe you'll find them useful.
Graphviz http://graphviz.org/ would be a good tool to achieve this.
It allows you to write your graph descriptions as simple text and it generates and lays out the graph. It can handle pretty large and complicated flows. Here is a simple example to give you an idea of the syntax:
digraph g {
NodeA -> NodeB;
}
In Visual Studio there is a tool called TaskList, which searches the code for TODO comments, compiles a list of them, and lets you go to a TODO item in the code by clicking on it in the list. Is there an equivalent tool in Matlab? Is there even a convention for TODO comments in Matlab?
What’s on my TODO list? is a post on 'Mike on the MATLAB Desktop'
concerning TODO lists.
Recent version of MATLAB can generate a report of TODO/FIXME. Check out this post, or read the relevant section in the documentation: Identifying Files with Reminder Annotations
There is no such tool in the MATLAB Editor, and no formal convention for the format of TODO comments.
EDIT: Apparently, there is such a tool on the MATLAB Desktop (as the other answers point out), but I guess it's not the easiest thing to find as I've somehow managed to miss it for years. One drawback (which the MathWorks appears to be planning to fix sometime in the future) is that you can only search individual directories.
In addition, there are a couple utilities submitted by users on the MathWorks File Exchange that you may want to check out which appear to perform similar functions:
Filegrep by Brett Shoelson
parseTags by Alexander Reinhold
searchtext by Kevin
You could try these out and compare them to the built-in MATLAB TODO report generator, or even use them as a guide to create your own TaskList-like functionality.
If you use a newer version of MATLAB and can't find the directory reports-drop down as explained by zellus
You can get to this report using the directory reports-drop down in the Current Directory Browser
http://blogs.mathworks.com/desktop/2008/03/17/whats-on-my-todo-list/,
you need to navigate to the context menu of the Current Folder view as shown in the following screenshot: (due to not sufficient reputation, I unfortunately cannot show the screenshot here directly)

How do I use Perl to create graphs?
I'm running scheduled job that creates text reports. I'd like to move this to the next step (for the management) and also create some graphs that go along with this. Is this possible / feasible? It'd be great if I could do this using Office some how.
update: solutions i'm going to investigate in this order
Spreadsheet::WriteExcel (this seems to now have changed from the last time i investigated this .... wait, this was suggested by the author of the module. cool.)
GD Graph - this is now available for ActivePerl(wasn't last time i looked)
SVG
Open Charts look interesting.
Chartdirector
GD and GD::Graph are probably your best bets, you can use them to create images that you can then embed into whatever you need.
All of the methods mentioned above are really good, but personally I like SVG::TT::Graph. I really like the power that SVG gives you to draw really nice-looking graphs.
Also you can take a look at Google Charts CPAN module
use Google::Chart;
my $chart = Google::Chart->new(
type => "Bar",
data => [ 1, 2, 3, 4, 5 ]
);
print $chart->as_uri, "\n"; # or simply print $chart, "\n"
$chart->render_to_file( filename => 'filename.png' );
At work we have used the excellent Chartdirector.
It's not free, but is very cheap (maybe 50 bucks or so). The cost is well worth it, as the API and docs are both excellent (way better than GD!), so easily saved more than that amount of my time.
There's also a free version, which includes a small yellow banner advertising the product on each chart - to be honest if this is for personal use, you can go for that as it's really not very intrusive at all.
Chartdirector is available for lots of platforms (Win, Linux, Solaris, BSD, OSX) and has an API for lots of languages, too (Perl, ASP, .NET, Java, PHP, Python, Ruby, C++).
The output is easy on the eye, as you can see at their examples page.
Sorry for blowing my own trumpet, but you might be interested to have a look some slides I did for a short presentation about Graphing With Perl.
It mentions some of the suggestions here, but also gives you some code snippets that you might be able to use to help you get the most of what you're doing.
Depending on the complexity of your graph, simply generating a command file for Gnuplot—or GraphViz/Dotty, depending on what kind of graph you are referring to—might do the trick?
The Perl module Spreadsheet::WriteExcel allows you to create Excel workbooks that include charts.
You first have to create the type of chart that you want in Excel and then extract it out using a utility called chartex which is installed with Spreadsheet::WriteExcel.
The chart template can then be added to a new workbook and made to reference new data.
The documentation is here and there are several examples in the charts directory of the distro.
The mechanism is a little inflexible however and the it is sometimes tricky to get the exact result that you want.
Haven't tried it yet but Chart::Clicker looks quite nifty.
I think it uses the Cairo graphic library (alternative to GD) but is actually built on top of Graphics::Primitive which is an "interesting" graphics agnostic package.
The author in question (GPHAT) seems to be putting together some integrated tools for producing reports... http://www.onemogin.com/blog/582-pixels-and-painting-my-recent-cpan-releases
On a side note... have used both ChartDirector and OFC and both are good (especially if web based).
Spreadsheet::WriteExcel::Chart
You might need something like strawberry or vanilla Perl to get this to compile. Or PPM might have the module.
Tutorial link:
http://search.cpan.org/dist/Spreadsheet-WriteExcel/charts/charts.pod
It won't work with Office, but I really like Chart::OFC which will create Open Flash Charts. Very slick looking and easy to use.
It depends to a great extent what sort of graphs (the look of them), and the data-source. I've had some good result by using the YUI Charts and feeding them some JSON style versions of the original source data. Rolling over a live chart for exact values is quite easy for example. There are plenty of examples on the developer pages.
If you're set on doing this in MS Office you can use the Win32::OLE module to control Excel via OLE. Be warned, that this tends to run slowly and it can be difficult to find documentation for Excel's API. On the plus side, it allows you to do pretty much everything that you can do manually.
Metaprograming of course! Output an R script that creates the graph.
PGPlot does great graphs. There are some examples here. It works fine with Perl 5.8.8 but is broken in 5.10.0
Spreadsheet::WriteExcel will let you just get the data into Excel, then write Excel equations for the graphs.
I wrote a script to export twitter friends as foaf rdf description. Now I'm looking for a tool to visualize the friend networks. I tried http://foafscape.berlios.de/ but for 300+ Nodes it is really slow and does a bad job on auto formatting.
Any hints for good graph visualization tools? It's ok if they do not support foaf directly, but they should be able to use images for graph nodes and be able to display large graphs. Linux support would be nice.
Oh, and I'm searching for an interactive tool where I can move nodes by hand.
Update: Thanks for your input. I know graphviz and for static images it is really great. But for large datasets I need to be able to select nodes and highlight all neighbours.
Prefuse looks great: http://prefuse.org/gallery/graphview/
trough prefuse I found vizster, which is exactly what I search (just need to find some sourcecode) http://jheer.org/vizster/
perhaps the prefuse visualization toolkit might help you. It's based on Java and has many sample apps including a graph viewer.
You could try Graphviz. It runs on Linux, Windows and Mac OS X and it will generate an image (PNG, PS, etc) of the graph. You will have to transform your foaf data into its own custom language, but it's pretty easy to learn.
I don't know of any program that auto-generates graph visualizations and allows you to interactively adjust nodes, but Graphviz is a really popular tool for graph visualization. It can export to SVG so you can edit the result in your favorite vector graphics editor.
As recommended by other posters, definitely Graphviz. It takes an input file, let's call it foaf.dot, in the following format:
graph G {
"George Formby" [shape=custom, shapefile="file:formby.png"];
"Michael Jackson" [shape=custom, shapefile="file:jackson.png"];
"George Formby" -- "Michael Jackson";
"Fred Flinstone" -- "Michael Jackson";
"Michael Jackson" -- "Steve McQueen";
}
Note that this file describes an undirected graph (hopefully your friendships are reciprocal). The syntax for directed graphs is similar.
In order to output your graph to a pdf file (assuming that you have already installed graphviz) run the following command
dot -Tpdf foaf.dot > foaf.pdf
Graphviz supports a number of output formats other than pdf, see its documentation for details.
I find that the 'dot' program usually provides the best output results, however graphviz contains a total of 5 layout programs. From the documentation:
dot - filter for drawing directed graphs
neato - filter for drawing undirected graphs
twopi - filter for radial layouts of graphs
circo - filter for circular layout of graphs
fdp - filter for drawing undirected graphs
I previously recommended Graphviz, but thought I should add another recommendation now that I have used Gephi, a newer tool than a lot of the stuff here. It's a very powerful interactive graph exploration tool which I have found much more usable and much faster than a lot of the alternatives here.
Try using Google Social Graph. In one of the talks at dConstruct08 last week there was a social graph showing the friend connections of Robert Scoble.
http://code.google.com/apis/socialgraph/
http://dconstruct.org/2008
If you're using Java, you could use JGraph.
I know Adobe Flex has a few graph visualization components out there, and of course that would enable the app to run on Flash which has an excellent penetration rate into your potential userbase. I'd Google up the Flex SpringGraph component, and check that out. There are a ton of graphing components in the wild for Flex, both paid and free versions.
Just one SpringGraph off the top of my head:
http://www.adobe.com/cfusion/exchange/index.cfm?event=extensionDetail&extid=1048510
check this forum: http://goosebumps4all.net/34all/bb/forumdisplay.php?fid=28
for some flare examples, there is a friend of a friend graph around there.
have you tried the Python-based IDE NodeBox (1.0)? That's what I used to generate these: http://givememydata.com/#images
vizster looks cool though, I'll check out that.
For large graphs, Gephi (http://gephi.org/) is very popular. It is highly customisable, with lots of layout and presentation options.
