All, I've got a 3-d matrix, sum_total(:,:,i) "i" is in a loop, and can be anything from 20 to 100, therefore making the length unknown until after the loop is finished.
Does anyone know how I might add all the matrices of the variable together to make a single matrix? I tried "cumsum" with no luck.

A=rand(3,4,5);
B=sum(A,3); % sum at the third dimension.
