How to do 3D matrix multiplication

I have a matrix A of size [56X32X10] and a matrix B of size [32X32X10]. How to multiply these two matrices such that the resultant matrix will be of size [56X32X10].

I used C=A.*B.

However its showing error "Arrays have incompatible sizes for this operation."

Answer 1

[Bruno Luong]

A = rand(56,32,10);
B = rand(32,32,10);

C = pagemtimes(A,B);

size(C)

ans = 1x3

56 32 10
