Multiplying m*m*N matrix internally

I have a matrix A with dimensions 2*2*N, and I would like to multiply each 2*2 'slice' of the matrix together to end up with a final 2*2 matrix. I've tried using prod but I haven't had much luck. Is there a better way, or a particular syntax to use? Thanks!

prod
performs element-wise multiplication.
If you want matrix multiplication, you can use something like :
A = rand(2,2,2);
res = A(:,:,1);
for i = 2:size(A,3)
res = res*A(:,:,i);
end
