MATLAB Function Reference

cputime - Elapsed CPU time

Syntax

cputime

Description

cputime returns the total CPU time (in seconds) used by your MATLAB^® application from the time it was started. This number can overflow the internal representation and wrap around.

Remarks

Although it is possible to measure performance using the cputime function, it is recommended that you use the tic and toc functions for this purpose exclusively. See Using tic and toc Versus the cputime Function in the MATLAB Programming Fundamentals documentation for more information.

Examples

The following code returns the CPU time used to run surf(peaks(40)).

t = cputime; surf(peaks(40)); e = cputime-t

e =
     0.4667
