How to insert an input in a constant in simulink?

Hello, I have an input in simulink coming from another system. This input must be used as element in a matrix. The obtained matrix must then used to make the cross product with anther vector. How can i do it?

Another way to say is that i need a matrix in simulink that accept inputs to make calculations with other inputs. Do you have a solution?
