Choosing a function handle from a group of function handles

Hello,

Assume that we have saved many function handles f_1_1, f_1_2,f_1_3, ..., f_2_1,f_2_2,f_2_3, .... in a folder. Now, assume also

that natural numbers m and n are given. Now, I want to define a function handle f as f = f_m_n . How to do this? (I mean, I want to

do this in a code in a for-loop).

Thanks,

Babak

Please explain what it means to save a function handle in a folder.

Have you saved a function handle (which is a class of variable) in a mat-file in a folder?

Have you saved a function (which is MATLAB code) in an m-file in a folder?

Something else?

Sorry if my explanation was not enough.

The functions are saved as m-files. If I know that m=3, n=4 then I can manually type f = f_3_4. But, how

to do this in a for-loop?

The only think I can do is as bellow

filename = strcat(['f_' num2str(m) '_' num2str(m)]);

but then I get f = 'f_3_4' not f = f_3_4.

I hope I was clear?

s = sprintf('f_%d_%d',m,n);
f = str2func(s);

Yes. Thanks a lot!
