process = subprocess.Popen(command.split(), 
                           stdout = subprocess.PIPE, 
                           stderr = subprocess.PIPE, 
                           shell = self.shell)
stdout, stderr = process.communicate()

matlab -nosplash -nodesktop -r run(\'%s\') -logfile %s'

First %s is program, second %s is log.

EDIT: Realized I also have a try/catch in my .m script. If you want the try/catch on the command line, use the following.

matlab -nosplash -nodesktop -r "try run(\'%s\'); catch e, fprintf(getReport(e)); end; quit" -logfile %s'

Seems that the cross-polar project encounters a similar issue. Details in this post and the followings.

@Houdanait if you have some time and are willing to explore this issue that would be awesome!

from gslab_python.

Yes ! @zkashner

@zkashner @yu-jia-wang, linking this with fix_latex_error and i might have a suggestion for this

from gslab_python.

Hi @yu-jia-wang, thanks for offering to check that the suggested change for Latex indeed works for Matlab as well. I have tried faking an error on a .m file and it worked. It would be great if we could actually test this on a repo with an existing hanging Matlab issue to make sure this work. We have just merged it to gslab repo so you should be able to check it out.
There is now a time out option in ProgramDirective.py (l.115 here ) which should lead to exit when an app is hanging.

Let me know if this worked!! Thanks!
