Hello, I'm designing a GUI involving callings to external functions (.exe) (e.g. system('doThis.exe') ) Those functions produce a lot of output to the MatLab command line and I'd like to simply divert them to/reproduce them in a textbox in my GUI. Is there a simple way to do this? I am using GUIDE but my textbox is created programmaticaly.
Thanks in advance.

If you do not need to have it happen as the output is produced, then assign the output of system() to a variable and display that variable. The variable will not be available until the command finishes.

Thanks. I've just tried. it works but the results are not what I expected. The output is simply '0', not the useful output text I see in the command line as the external function is running... and is there a way to reproduce the text on the fly?

[status, cmdout] = system('doThis.exe');
then cmdout is the string.
Capturing the output on-the-fly is messy. I think it was discussed about 3 weeks ago, but I do not seem to find the discussion.

Thank you again, that worked fine :) I think I'll forget the on-the-fly reproduction for now at least.
