Element-wise product in Simulink

I would like to perform an element-wise multiplication (Hadamard product) between 2 matrices in Simulink. The "multiply" block only allows for element-wise multiplication when the dimensions of both arguments are equal. For example, I would like to perform the following in Simulink (which works in MATLAB):
a = [1,2,3
4,5,6
7,8,9];
b = [1,2,3];
c = a.*b; % element-wise multiplication [3X3] x [1X3]
The only method I have found that works in Simulink is to copy each row of the b vector to produce 2 matrices that have the same dimensions:
a = [1,2,3
4,5,6
7,8,9];
b = [1,2,3
1,2,3
1,2,3];
c = a.*b;
This method is not ideal because my matrices are very large and I am trying to avoid duplicating the b vector to save memory.

I wonder if you could get somewhere switching between sample based and frame based ?

Desired can be achieved using For Each or For Iterator subsystem
