bbinary5d

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

Installation

npm install @stdlib/array-base-broadcasted-binary5d

Usage

var bbinary5d = require( '@stdlib/array-base-broadcasted-binary5d' );

bbinary5d( arrays, shapes, fcn )

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

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

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

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

bbinary5d( [ x, y, z ], shapes, add );
// z => [ [ [ [ [ 4.0, 5.0 ], [ 5.0, 6.0 ] ], [ [ 4.0, 5.0 ], [ 5.0, 6.0 ] ] ] ] ]

The function accepts the following arguments:

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

Notes

• The input and output array shapes must be broadcast compatible.

Examples

var discreteUniform = require( '@stdlib/random-base-discrete-uniform' ).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 bbinary5d = require( '@stdlib/array-base-broadcasted-binary5d' );

var shapes = [
    [ 1, 1, 1, 1, 3 ],
    [ 1, 1, 3, 1, 1 ],
    [ 1, 1, 3, 3, 3 ]
];

var x = filled5dBy( shapes[ 0 ], discreteUniform( -100, 100 ) );
console.log( x );

var y = filled5dBy( shapes[ 1 ], discreteUniform( -100, 100 ) );
console.log( y );

var z = zeros5d( shapes[ 2 ] );
console.log( z );

bbinary5d( [ x, y, z ], shapes, add );
console.log( z );
