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.

The function starts a new cmd/shell process, executes command , exits the process, and returns to the MATLAB® process. Updates to the system environment made by command are not visible to MATLAB. [ status , cmdout ] = system( command ) also returns the output of the command to cmdout .
You can execute operating system commands from the MATLAB® command line using the ! operator or the system function.
Otherwise, MATLAB uses the Bourne shell.
Go to the Editor tab and click Run . MATLAB® displays the list of commands available for running the function. Click the last item in the list and replace the text type code to run with a call to the function including the required input arguments.
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.
