evalc

Evaluate a string and capture its console output.

Syntax

result = evalc(expression)
[result, a1, a2, ...] = evalc(expression)

Description

Executes expression and captures everything that would have been printed to the console as the string result. Side-effects on workspace variables still occur. Useful for testing functions whose primary effect is disp() / printf() output.

Example

out = evalc('disp(magic(3))')   % out captures the printed matrix
