kron_product

Computes the Kronecker product for two-dimensional matrices.

Available in version 5.1.0 and later.

Prototype

	function kron_product (
		a [*][*] : numeric,  
		b [*][*] : numeric   
	)

	return_val  :  float or double

Arguments

A two-dimensional array dimensioned na1 x na2.

A two-dimensional array dimensioned nb1 x nb2.

Return value

The return value will be dimensioned (na1*nb1) x (na2*nb2). The type will be double if any of the input is double, and float otherwise.

Description

This function computes the Kronecker product.

Examples

Example 1

      
      a  = (/ (/1,2/) \
            , (/3,4/) /)

      b  = (/ (/0,5/) \
            , (/6,7/) /)

      z = kron_product( a,b )
      print( z )

The (edited) output is:

     Variable: z
