MATLAB: How to multiply N dimensional matrices

Question

I am trying to multiply a 3x3xn matrix with a 3x4xn matrix.

I tried a for loop but it says that the matrix dimensions do not agree.

The new matrix that I need is just the product of the first A(:,:,i)*B(:,:,i) which should work but in my case it isn't

Answer 1

C = zeros(3,4,n) ; 
for i = 1:n
    C(:,:,i) = A(:,:,i)*B(:,:,i) ; 
end
