KRON matrix function
Description
KRON(A,B) Returns the Kronecker tensor product of matrices A and B.
If A is an m × n matrix and B is a p × q matrix, then the Kronecker tensor product of A and B is a mp × nq matrix formed by multiplying each element of A with matrix B.
$$ \mathbf{A}\otimes\mathbf{B} = \begin{bmatrix} a_{11} \mathbf{B} & \cdots & a_{1n}\mathbf{B} \\ \vdots & \ddots & \vdots \\ a_{m1} \mathbf{B} & \cdots & a_{mn} \mathbf{B} \end{bmatrix} $$
