MATLAB: Can I add additional non-matlab executables to the compiled Matlab application on Linux

MATLAB Compilermcc

FYI, I am using RedHat Linux 6.1 and Matlab 2012a. I have a Matlab function that calls an external executable with a system command among lots of other things. Example:

[s,w] = system('nonMatlabEXE');

I have compiled my Matlab function using:

 mcc -m myFunc.m -a /path/to/nonMatlabEXE/* -a /path/to/dataFiles -I /other/required/paths/

This generates the executable 'myFunc', a 'run_myFunc.sh' script, a 'readme.txt', and a mccExludedFiles.log'. However when I run my Matlab compiled exec via Linux command prompt:

run_myFunc.sh /path/to/mcr/

I get "nonMatlabEXE: command not found" errors when I hit that the line with the system command.

So my questions are:

Is it possible to package the non-Matlab executable with my Matlab Compiled app? If not what are my best options? Should I just co-located the non-Matlab executables with the mcc output 'myFunc' and/or modify the shell script 'run_myFunc.sh' to include additional enviroment PATH variables?

Thanks,

You have added the executables to the package. They will get expanded when the stand-alone executable is run. However, the directory they end up in is not necessarily on the execution path methods specified by your operating system. You should build the path to the appropriate location into a string and specify it as part of the system() command. You will likely find ctfroot() useful for building the path.

Please read more about path management for stand-alone executables in this blog post

You can use an icon on the Linux desktop to execute a compiled application by adding a shell script in the same directory with the application. The shell script should look as follows:

 #!/bin/csh
 setenv LD_LIBRARY_PATH
 ./yourprog

where yourprog is the name of the stand-alone executable.

MATLAB: Is there a way to not block the MATLAB command line when calling a DOS console program using the DOS or SYSTEM command

To prevent the DOS command from blocking MATLAB execution, run the DOS program in its own console window.

The following piece of code illustrates this:

dos('my_DOS_program &');

The '&' at the end of the string specifies that this DOS command must run in its own console window and not in MATLAB.

Using this allows MATLAB to execute while the DOS program runs.
