How do I run a linux module from the Command line in Matlab?

I am running Matlab on a linux machine. I would like to run a linux module in a Matlab script. When I type "! module" in the command line Matlab retruns "/bin/bash: module command not found" When I open a linux terminal in the same directory the command "module" works as expeted. What am I doing wrong?

Can Matlab run linux modules?

Call the command through the MATLAB function unix()

doc unix

from the MATLAB command line.

[Kurtis Ford]

That funciton yields the same error. I type "unix('module avail')" and Matlab returnes "/bin/bash: module: command not found"

If you are; I'm missing it!

What happens with:

unix('pwd')

unix('ls')

?

[Kurtis Ford]

All of those work just fine. I just talked to the tech guys and they say it may be related to an automonous systems issue that our system is having.

Perhaps the PATH is incomplete? "getenv('PATH')" could reveal this, I assume.

It sounds like the environment that you get in your command shell and the one that's launching MATLAB is different. If you compare outputs "set" in your terminal and from unix('set') in MATLAB, you'll likely find that there are differing path settings that prevent "module" from being found.

A quick test you could do is to run "which module" in your terminal. This will tell you where "module" lives. Then you can see if that directory is on the PATH in the output of the unix('set') command from MATLAB.

Why these would differ can be any of a number of reasons, but hopefully this would help your systems people sort it out.
