I want to implenet timeit() function to find the machine time for the execution of the m-file 'fpa1.m'. But when I run the attached 'main.m', it gives me the following error:

Error using timeit

First argument must be a function handle that takes no input argument.

Error in main (line 6)

fprintf('time taken by fpa1 = %e seconds', timeit(@fpa1,3))

在 MATLAB Online 中打开

fcn = @() fpa1(10,0.8,2000,4,[-90 -90 -90 -90],[90 90 90 90],@(b)myfunction(b,u,Noise));
timeit(fcn, 3)

The original version of the timeit() function is in the File Exchange. You could load it from there and modify it.

But suppose it gives different output results on different timing iterations, then which version should be output?

Thanks a lot dear Walter Roberson for your kind response. Actually, I have already seached there, the code of the timeit() has been removed from the File Exchange. So, the conclusion is that first, I will run the code for the estimation of outputs and then I will run the code for timeit() because the 'tic-toc' gives wrong timing for estimating different number of values. Thanks a lot once again dear Walter Roberson for your kind response.
