redirect system() output on the fly to estimate progress of external cmd

Question

Is there a 'non-messy' (or OK, any?) way to catch the [status, output] = system() on the fly?

Basically I have to run an external tool in C++ (at the moment, modifying it is not an option) to create some file.

In the terminal, progress is returned on the fly. Obviously, in MATLAB (2014b, OS X 10.10.5) the output is only available after completion.

The idea is simply to catch it on the fly such that information and progress can be shown in a uitable/uiwhatever.

(I'm sorry if this was already asked; I searched for this issue but didn't find an answer yet...)

There is no non-messy way.

You will need to do a process open. You can use popen() from the File Exchange

As expected indeed.

Thanks, I'll have a look at it.
