Running a bash script from MATLAB

Hi,

I have a .sh script that needs to be run from MATLAB to open another program.

The command (/s/test2.sh) typed directly into the UNIX terminal works successfully.

The problem is: when running the same command in MATLAB, using the "system" and "unix" function, MATLAB returns the status '0' but the .sh script does not open the other program. I know the script was running because it prints some variables.

Could someone help me with this problem?

Thanks in advance.

When you system() or unix() then matlab does not use a login shell, so some initialization might not be done. Aliases might not be set up for example.

Also because it is not a login shell, your shell PATH and LD_LIBRARY_PATH or DYLD_LIBRARY_PATH might not have been set the way you expect.

You might need to

export VARIABLE=VALUE bash /s/test2.sh

or something like that
