Usage

var cartesianProduct = require( '@stdlib/array/cartesian-product' );

cartesianProduct( x1, x2 )

Returns the Cartesian product.

var x1 = [ 1, 2, 3 ];
var x2 = [ 4, 5 ];

var out = cartesianProduct( x1, x2 );
// returns [ [ 1, 4 ], [ 1, 5 ], [ 2, 4 ], [ 2, 5 ], [ 3, 4 ], [ 3, 5 ] ]

If provided one or more empty arrays, the function returns an empty array.

var x1 = [ 1, 2, 3, 4 ];
var x2 = [];

var out = cartesianProduct( x1, x2 );
// returns []

Examples

var linspace = require( '@stdlib/array/linspace' );
var cartesianProduct = require( '@stdlib/array/cartesian-product' );

var x1 = linspace( 0, 5, 6 );
var x2 = linspace( 10, 15, 6 );

var out = cartesianProduct( x1, x2 );
// returns [ [ 0, 10 ], [ 0, 11 ], ..., [ 5, 14 ], [ 5, 15 ] ]
