Matrix operations with continuous variable

Hello everybody,

I want to multiply two matrices, which contains a continuous variable q and some constants.

To solve this problem, I must use the numerically way.

When I fill the matrix, I get this problem "Dimensions of arrays being concatenated are not consistent.". I think this comes from the constants in the matrices.

Another problem is how can I mutiply the matrices stepwise for each value of q?

Is there an easy way to do this?

q = 4:2:10; % q is a continuous variable

B = [q,  cos(q) ; 
    5,  3*q ;
     2*q, 8]
    
  
 C = [q,  sin(q) ; 
    2,  3*q ;
     q, cos(q)]
   
  A = B .* C

Best regards!

B = [q,  cos(q) ; 
    5*ones(size(q)),  3*q ;
    2*q, 8*ones(size(q))]
