Hello,
When I run a function handle its execution time is initially very long but in the second, third, etc runs its execution time is normal (sometimes, however, I see that the lnog initial execution time will happen again in later runs but this does not happen very frequently).I have seen this problem when I work with symbolic expressions but did not expect to see this in matlabfunctions. I would like to know whether there is a way to avoid this? Or, is there something like 'loading the file' (or similar concepts) prior to executing the matlab function to avoid this?
In the following, you see an example about my question (the matlab function EZ_CC_3_11 is attached).
n=10;
Dm0=rand(1,n);Dm1=rand(1,n);Dm0=rand(1,n);Dm2=rand(1,n);Dm3=rand(1,n);Ds0=rand(1,n);Ds1=rand(1,n);Ds2=rand(1,n);Ds3=rand(1,n);
tic;EZ_CC_3_11(Dm0,Dm1,Dm2,Dm3,Ds0,Ds1,Ds2,Ds3);toc;
Elapsed time is 111.170418 seconds.
tic;EZ_CC_3_11(Dm0,Dm1,Dm2,Dm3,Ds0,Ds1,Ds2,Ds3);toc;
Elapsed time is 0.033134 seconds.
tic;EZ_CC_3_11(Dm0,Dm1,Dm2,Dm3,Ds0,Ds1,Ds2,Ds3);toc;
Elapsed time is 0.029289 seconds.
Thanks,
Babak
