Mean of several variables

Hello i have problem. How I can solve mean of sever variables? I have variables from test1 to test100, these variables are matrices 315x573.

I know that mean is for example: pokus=mean(test1(:))

And how use for cycle to replace number of variable and make mean these variable?

When i use:

for i=1:100
   pokus(i,:)=mean(eval(['test' num2str(i)]),1);
% prumer=mean(pokus,2); 
end

I receive error:

Subscripted assignment dimension mismatch.

Somehow you got yourself into a real mess. How on earth did you have 100 variables names test1 through test100? I would try to avoid that in the first place. If you put the hundred matrices into a single 3D array instead, it would be so easy - a single line of code. No for loop and no (hated) eval function.

Your code is correct .Kindly verify size of "pokus" if you initialized

I have found error, one variable have different dimension. Now it work fine :)
