Element wise multiplication of a 4D Matrix

Say I have a 4D matrix called X_values the size of 3x3x3x10. I wanted to do an element wise multiplication along the 4th dimension and obtain a 3x3x3 matrix at the end. Any recommendation on how to do it?

A confusing question. MAYBE you are asking how to take the product of the elements along the 4th dimension? That is consistent with what you are asking for a result. And that is trivial. Just use prod. It works just like sum.

A = rand(3,3,3,10); % just create a matrix of the right shape

B = prod(A,4);
size(B)

ans = 1×3

3 3 3
