Elapsed CPU time
cputime
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.
The following code returns the CPU time used to run surf(peaks(40)).
t = cputime;
surf(peaks(40));
e = cputime-t
e =
0.4667 To measure performance, it is recommended that you use the timeit or tic and toc functions. For more information,
see Using tic and toc Versus
the cputime Function.
