# kron

Kronecker product (.*.)

## Calling Sequence

    kron(A,B)
                A.*.B

## Description

`kron(A,B)` or `A.*.B` returns the Kronecker tensor product of two matrices `A` and `B`. The resulting matrix has the following block form:

If `A` is a `m x n` matrix and `B` a `p x q` matrix then `A.*.B` is a `(m*p) x (n*q)` matrix.

`A` and `B` can be sparse matrices.

## Examples

    A=[1,2;3,4];
    kron(A,A)
    A.*.A
    sparse(A).*.sparse(A)
    A(1,1)=%i;
    kron(A,A)
