How to multiply row and column vectors in Simulink

I would like to multiply a row and a column vector using Simulink.

Example in MATLAB:

a = [11 12 13 14 15];
b = [1;2;3];
c=a.*b

c = 3×5

11 12 13 14 15 22 24 26 28 30 33 36 39 42 45

I could not perform this simple operation using Simulink block:

What am I doing wrong, how can I make row-column vector multiplication via Simulink?

Thank you in advance!

Your MATLAB code takes advantage of implicit expansion. This feature is not available in Simulink. You'll need to update your model to convert the vectors to matrices with compatible sizes.
