Question

Say that, on a MATLAB interactive session, I call a function from a third party library output = long_execution(input). This function prints information via disp statements to the command window. I would like to capture the output of such disp statements on a text string that I can manipulate in MATLAB.

Is there a (hopefully easy) way of redirecting the output of disp to a text string? If so, how would you do it? (maybe via the overlading of disp?)

Answer 1

You can use evalc function to capture disp outputs. For example,

    [T, output] = evalc('long_execution(input)');

Anything that would normally go to command window is captured into the output T.
