KRON

Purpose:

Returns the Kronecker tensor product of two matrices.

KRON(a, b)

a	-	A matrix.
b	-	A matrix

A matrix.

a = {{ 1, 2},

{-1, -2}}

b = {{10, 20},

{30, 40},

{50, 60}}

c = kron(a, b)

c == {{ 10, 20, 20, 40},

{ 30, 40, 60, 80},

{ 50, 60, 100, 120},

{-10, -20, -20, -40},

{-30, -40, -60, -80},

{-50, -60, -100, -120}}

For m = numrows(a) and n = numcols(b), kron(a, b) returns the array formed by the following product:

{{a[1, 1] * b, a[1, 2] * b, ... a[1, n] * b},

{a[2, 1] * b, a[2, 2] * b, ... a[2, n] * b},

...

{a[m, 1] * b, a[m, 2] * b, ... a[m, n] * b}}
