Suppose I have a code running in a loop I have done some operations and I create a matrix in the loop, that matrix has the same size in every iteration. How do i calculate the number of elemens of the matrix only for the first iteration and not for every iteration since i know that it will be the same for every iteration? I want to avoid using ifelse statements.

Use "isempty":
I = rand(4,5);r=[]; c=[];
for i=1:10
if isempty(r) || isempty(c)
[r,c]=size(I);
end
end
