Problem Statement

Implement the   Kronecker product   of two matrices (arbitrary sized) resulting in a block matrix.

Show results for each of the following two samples:

Sample 1 (from Wikipedia): Sample 2:

See implementations and results below in JavaScript and PARI/GP languages.

Let's start with the solution:

USING: kernel math.matrices.extras prettyprint ;

{ { 1 2 } { 3 4 } }
{ { 0 5 } { 6 7 } }
{ { 0 1 0 } { 1 1 1 } { 0 1 0 } }
{ { 1 1 1 1 } { 1 0 0 1 } { 1 1 1 1 } }
