# Linear Operators of Matrices

Hi there,

As you know, we can represent a Linear vector operator as a matrix product, i.e., if T(u) = v, there is a matrix A that u = A.v.

What about a linear operator of matrices. I have a T(X) = b where X belongs to R^n_1Xn_2 and b belongs to R^p. What is a suitable representation of this operator? Is this tensor or Kronecker product?

Best wishes,
Reza
