I'm working on 2 branches in SVN and I'd like to have 2 shortcuts (or 2 .bat files) to start matlab with path correctly defined upon the branch I'm currently working with. For instance:
[Matlab-trunk.bat] ==> Would look for some pathdef-trunk.m
~matlabroot\toolbox\matlab\apps
~matlabroot\toolbox\matlab\audiovideo
~code\trunk\MyToolboxes\Common
~code\trunk\MyToolboxes\Miscellaneous
~code\trunk\MyToolboxes\etc\etc ...
[Matlab-BranchLala.bat] ==> Would look for some pathdef-lala.m
~matlabroot\toolbox\matlab\apps
~matlabroot\toolbox\matlab\audiovideo
~code\branchlala\MyToolboxes\Common
~code\branchlala\MyToolboxes\Miscellaneous
~code\branchlala\MyToolboxes\etc\etc ...
I have read this thread:
How to run two MATLAB instances simultaneously with different pathdef's?
And I like the solution where I would simply have to define for MATLABPATH environment variable before to start Matlab ... but it seems this only works for Unix\Mac platforms ... maybe I should mimic similar idea by manually editing the matlabrc.m file ... or maybe you have a better idea ?
EDIT
Humm ... maybe I should dynamically switch startup.m file before to start and add a matlabpath(...) in there ... but I don't know where it is stored, the command userpath is returning `` on my PC.
NB1: I'm working with Matlab R2013b on a PC platform
NB2: I cannot move to git do in-place branch-switching for now on (this was one solution I though about).
You can define different startup folders for each of the shortcuts.
Then, at each different startup folder define pathdef.m file with the different paths.

I have a software that has multiple GUIs. To organize things better (or at least that was my thought), I have created several folders within the root directory as it can be seen in this image.
Within the folders i have both files with different formats and also some Matlab scripts.
When creating the Matlab executable using the Application compiler, and after selecting the main file, Matlab does not directly detected that these same folders are important for the code to run. Therefore I decided to add the folders manually.
Once the setup is created and installed, by running the application within the Matlab environment, I was able to debug one possible issue why the software is not running.
As you can see in the first image, the "play.png" is within the Images folder.
My question is pretty straight forward: how to force the Matlab Compiler to learn that all these folders are to be included in the setup? Not only to be included but their paths'
Two things could be going on:
You are not including the files in the package.
Make sure that you include them using the -a option of mcc:
mcc -m hello.m -a ./testdir/*
You can also use the GUI, of course, see here.
You are looking for the included files in the wrong place. Use ctfroot as the root of all paths in your code:
img_file_name = fullfile(ctfroot,'Images','brain.jpg'));
Check the unpacked CTF file (it is automatically unpacked when executed) to see the directory structure in it. ctfroot points to the root of the unpacked CTF file.
PS: This blog post might give you some more pointers.
I'm automating my build process, but I wasn't able to change the model_target_rtw folder to something different.
I'm not talking about CodegenFolder, but about the folder that's created inside it during compilation.
I'm currently working this around by renaming the folder after compilation, but it would be grate to remove that step.
The folder you are referring to is the RTW (Real Time Workshop) BuildDirectory.
You can get the value of BuildDirectory by running the command:
RTW.getBuildDir('MyModel')
See:
https://se.mathworks.com/matlabcentral/answers/274082-how-can-i-change-the-build-folder-of-a-model
Also look at this question:
Save generated code in a special folder in "rtwbuild"
If you run this command in MATLAB:
set_param(0, 'CodeGenFolder', 'C:\MyBuildDir')
and then run the RTW.getBuildDir command again you will see that the BuildDirectory has changed.
I am using Netbeans 8.0.2 and phpdocumentor 2.8.2 on a windows 7 platform.
I would like to use custom phpdoc.dist.xml config files by project so I can specify framework directories and etc. to exclude from the generated doc. I also want to keep my Netbeans PHPDOC plugin config as generic as possible, without specific output directories, ignore options, config path parameters, etc., so on, so that that the config will apply to all my projects.
The phpdoc.dist.xml file works great. The doc generated is exactly what I want.
The problem or feature, and it seems to be a phpdocumentor one as it also applies from plain command line, is that the phpdoc.bat command (without a specific config parm) has to be run from the same root directory as the phpdoc.dist.xml file, or it ignores it. No problem if I'm using command line as I can change into that directory first, but I would like to use Netbeans. I have searched on this extensively and cannot find an answer.
I considered whether to modify the phpdocumentor files to insert cd /D path/to/myproject/dir to change the directory using some Netbeans variable to represent myproject/dir, but I could not find the right place in the code or the variable to use. Plus, then I'm supporting a custom mod to phpdocumentor.
I did find these directions for a PHPStorm setup, where the author specified a PHPStorm variable for the --config command line option to point to his custom phpdoc.dist.xml.
--config="$ProjectFileDir$/phpdoc.dist.xml"
If I could do the same in Netbeans like maybe "${BASE_DIR}/phpdoc.dist.xml" it would be great, but so far I haven't hit on anything Netbeans will recognize/pay attention to in the PhpDoc script: box.
I have also tried writing a wrapper .bat file to capture my own command line variable %1 and do the directory change to that before calling phpdoc.bat, but Netbeans throws and error and says that's not a valid .bat file. I cannot find any phpdocumentor parameter to configure by specific Netbeans project but the output directory. And I would prefer not to be defining a bunch of projects on subdirectories in Netbeans, just to address phpdocumentor.
Now I am out of ideas. Can anyone point me to a solution?
I am running a program on Matlab and I use spmd to parallelize my code.
The same code runs on 2 different PCs. One of them runs perfectly well, but the other doesn't and the Fatal Error occurs.
If I try to run a non-parallelized program, there are no errors. I don't know if there is a problem with this specific command or if I did something wrong myself.
Could it be related to the directories in which I have saved my code files?
If so then why does the non-parallelized program run?
I'm not sure if you still have this problem, but anyway...
The problem is with the path to preferences folder. So, you need to change it.
Mostly such error occurs if you don't have write access to this folder or its located in hidden folder.
To open the current path of the prefdir type winopen(prefdir) in matlab Command window. Then copy all files from this folder into new one (for instance C:\MATLABPreferences).
Now you need to change a path of the prefdif using .bat file with the following text:
fullfile (matlabroot, 'bin', 'matlab')
set MATLAB_PREFDIR=<New preference folder location>
"<MATLAB executable location>"
Example:
fullfile (matlabroot, 'bin', 'matlab')
set MATLAB_PREFDIR=C:\MATLABPreferences
"C:\Program Files\MATLAB\R2013b\bin\matlab.exe"
Run it and enjoy parallel computing with matlab.
More detailed explanation you can find here.
I've had problems with this, and so far the internet was not really useful. After hours of Googling, this turned out to be useful. You just need to add a new variable to your environmental variables (in case you are using Windows) named MATLAB_PREFDIR with the location of the preferred directory.
For me, it is C:\Users\Balázs\AppData\Roaming\MathWorks\MATLAB\R2014a, but you can get if you type prefdir into matlab's command line.
Can I set a workspace wide setting to add an environment variable to all future launchers created in the workspace?
Use Case
Our unit tests require an environment variable to guide the test to certain resources.
the variable varies with each version of our product
Options
- modify each junit launcher with the environment variable
- create start up script that sets variable and launches eclipse
- set globally
Ideally, I'd like to provide a way for users to set it once per workspace.
Does eclipse have a place to set an environment variable for all launchers?
Thanks
Peter
Only option which I can think of is similar to yours where you can create multiple shell scripts(linux) or batch files(windows) and set it up there. for ex -
I am giving examples for windows environment and same can be done for Linux as well -
for windows-
eclipse.exe -DvariableName1=value1 -DvariableName2=value2
As you want to pass different variables to different workspaces, you can also pass location of your workspace as part of arguments.
eclipse.exe -data <your_workspace_location> -DvariableName1=value1 -DvariableName2=value2
You can create multiple shortcuts of eclipse.exe in windows and place them on Desktop (for quick access) if needed. Each shortcut may point to a similar variant of above command with different workspace and different variables.
Hope this helps. Happy coding :)
I have a different approach for doing this on windows. This solution allows you to store a large number of environment variables to one place and apply them globally inside eclipse.
I have gitBash installed already, and associated in windows to execute .bash files
I set up a /c/Temp/.env file with lots of environment variables in the format
export VARIABLE=my value
I create an eclipse_startup.bash script that looks like this (and pin it to my start menu).
echo setting up env
. /c/Temp/.env
echo starting eclipse
/c/Users/me/eclipse-oxygen/eclipse/eclipse.exe
It has the disadvantage that I end up with a bash window open with eclipse, and I have to restart after changing the environment. On the plus side, my complex application has lengthy environment files already, so I can simply load them in and start.
