[R] Vectorize a series of Matrix Multiplications

Can I have some help in vectorizing a series of matrix multiplications? Toy Example mat_size=2; num_matrices=3; num_users=2 ToyArray=array(1,dim=c(mat_size,   mat_size, num_matrices, num_users)) /* So I open an 4-dim array to store 3  2 X 2 matrrices  for 2 users.  For each user I want to multip
