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:

              | A(1,1) B ..... A(1,n) B |
              |   .              .      |
    A .*. B = |   .              .      |   
              |   .              .      |
              | A(m,1) B ..... A(m,n) B |
    

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)
