在 MATLAB Online 中打开

tic;
% do stuff
toc;

Also, see cputime(), etime(), clock()

And PROFILE. Be aware that CPUTIME can lead to unexpected results if you run a multi-core machine. And CLOCK suffers from its connection to the real time clock: Changing the day-light-saving time or an automatic update of the clock via NTP can disturb the speed measurements.
