Strange results from tic / toc.

Asked by John Doe on 9 May 2013

I'm checking the running time of a function using tic/toc. I write the following in the command window (and execute it simultaneously):

res = checkFunc('case2736sp',1:3000);
Elapsed time is 0.080491 seconds.

where checkFunc returns a 2736x2500 full matrix.

What puzzles me is that I have to wait almost 20 seconds for the output saying the run time is only 80 ms.

Does anyone have a clue why this is?

Accepted answer

Are you sure 'checkFunc' does NOT do a tic somewhere in its code? Anyways, this would be a better way to test:

tx = tic; res = checkFunc('case2736sp',1:3000); toc(tx)
