About stdlib...
We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.
The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.
When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.
To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!
nCartesianProduct
Return the n-fold Cartesian product.
Installation
npm install @stdlib/array-base-n-cartesian-product
Usage
var nCartesianProduct = require( '@stdlib/array-base-n-cartesian-product' );
nCartesianProduct( x1, x2[, ...xN] )
Returns the n-fold Cartesian product.
var x1 = [ 1, 2, 3 ];
var x2 = [ 4, 5 ];
var out = nCartesianProduct( 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 = nCartesianProduct( x1, x2 );
// returns []
Examples
var linspace = require( '@stdlib/array-base-linspace' );
var nCartesianProduct = require( '@stdlib/array-base-n-cartesian-product' );
var x1 = linspace( 0, 5, 6 );
var x2 = linspace( 10, 15, 6 );
var x3 = linspace( 20, 25, 6 );
var out = nCartesianProduct( x1, x2, x3 );
// returns [ [ 0, 10, 20 ], [ 0, 10, 21 ], ... ]
Notice
This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
