Multiplying 3D array to 2D matrix error

Hi, I am trying to multiply a 72*51*51 3D array with a 51*51 2D matrix elementwise. How do I go about this using a for loop?

Thank you.

If A is your 72*52*52 array and B is your 52*52 matrix, then:

result = A .* repmat(permute(B,[3 1 2]),[size(A,1) 1 1]);

No need for a for loop.
