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!

mskbinary5d

Apply a binary callback to elements in two five-dimensional nested input arrays according to elements in a five-dimensional nested mask array and assign results to elements in a five-dimensional nested output array.

Installation

npm install @stdlib/array-base-mskbinary5d

Alternatively,

• To load the package in a website via a script tag without installation and bundlers, use the ES Module available on the esm branch (see README).
• If you are using Deno, visit the deno branch (see README for usage intructions).
• For use in Observable, or in browser/node environments, use the Universal Module Definition (UMD) build available on the umd branch (see README).

The branches.md file summarizes the available branches and displays a diagram illustrating their relationships.

To view installation and usage instructions specific to each branch build, be sure to explicitly navigate to the respective README files on each branch, as linked to above.

Usage

var mskbinary5d = require( '@stdlib/array-base-mskbinary5d' );

mskbinary5d( arrays, shape, fcn )

Applies a binary callback to elements in two five-dimensional nested input arrays according to elements in a five-dimensional nested mask array and assigns results to elements in a five-dimensional nested output array.

var add = require( '@stdlib/math-base-ops-add' );
var zeros5d = require( '@stdlib/array-base-zeros5d' );

var x = [ [ [ [ [ 1.0, 2.0 ], [ 3.0, 4.0 ] ] ] ] ];
var z = zeros5d( [ 1, 1, 1, 2, 2 ] );

var mask = [ [ [ [ [ 0, 1 ], [ 0, 0 ] ] ] ] ];

var shape = [ 1, 1, 1, 2, 2 ];

mskbinary5d( [ x, x, mask, z ], shape, add );
// z => [ [ [ [ [ 2.0, 0.0 ], [ 6.0, 8.0 ] ] ] ] ]

The function accepts the following arguments:

• arrays: array-like object containing two input nested arrays, an input nested mask array, and one output nested array.
• shape: array shape.
• fcn: binary function to apply.

Notes

• The function assumes that the input and output arrays have the same shape.

Examples

var discreteUniform = require( '@stdlib/random-base-discrete-uniform' ).factory;
var bernoulli = require( '@stdlib/random-base-bernoulli' ).factory;
var filled5dBy = require( '@stdlib/array-base-filled5d-by' );
var zeros5d = require( '@stdlib/array-base-zeros5d' );
var add = require( '@stdlib/math-base-ops-add' );
var mskbinary5d = require( '@stdlib/array-base-mskbinary5d' );

var shape = [ 1, 2, 1, 3, 3 ];

var x = filled5dBy( shape, discreteUniform( -100, 100 ) );
console.log( x );

var y = filled5dBy( shape, discreteUniform( -100, 100 ) );
console.log( y );

var mask = filled5dBy( shape, bernoulli( 0.5 ) );
console.log( mask );

var z = zeros5d( shape );
console.log( z );

mskbinary5d( [ x, y, mask, z ], shape, add );
console.log( z );
