can we implement matrix multiplication in simulink with known variables?

I have 2 variables, which is in 2 4*4 matrices which have to be multiplied to get the final result. I need to change the values of the variables for different conditions.

https://www.mathworks.com/help/simulink/slref/product.html with 'Multiplication' set to 'Matrix'

Everything else is setting up the appropriate signals and the control logic for changing the variables.
