Matlab system call

Question

If I want to call a script "filtermapq.sh" inside a matlab script. How would I go about calling it and then waiting for the script to finish before resuming the rest of the matlab code? I am not the best with matlab.

Currently I am using this command:

system(['./util/filtermapq.sh ' var1 var2 var3])

However, I don't think that the matlab code waits for this to finish before continuing.

I see that you found a solution, let me give you a bit more elegant one, which will make life easier for the future.

system(sprintf('./util/filtermapq.sh %s %s %s', var1, var2, var3))

This could also pass in numbers, for instance, or other cool stuff. Also, you could do this to help with debugging such issues.

command=sprintf('./util/filtermapq.sh %s %s %s',var1, var2, var3);
fprintf('%s\n',command);
system(command);

That will log out to the screen the exact command that you are attempting to run. If your system command doesn't work, copy/paste it into a command line window, see if it works there. If it doesn't figure out how to massage the text to make it work, and fix your code appropriately.
