SO basically , I need the product of these 2 variables for 20 iterations and then add the products. I tried using * and .* but that doesn't work.

In this formula you multiply with the squared norm of Phi, which is a scalar, not a matrix.

Hi Sagar
Try this code:
sum=0
for i=1:20
sum=sum+s(:,:,i).*(phi(:,:,i).^2)
end
It will work if the sizes of A and B match.
Cheers

Using "sum" as variable causes troubles frequently, because the builtin function sum() is not available afterwards. Better avoid shadowing of builtin functions by using different names.
