@stdlib/array-base-broadcasted-unary5d v0.2.1

bunary5d

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

Installation

npm install @stdlib/array-base-broadcasted-unary5d

Usage

var bunary5d = require( '@stdlib/array-base-broadcasted-unary5d' );

bunary5d( arrays, shapes, fcn )

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

var zeros5d = require( '@stdlib/array-base-zeros5d' );
var abs = require( '@stdlib/math-base-special-abs' );

var x = [ [ [ [ [ -1.0, -2.0 ] ] ] ] ];
var y = zeros5d( [ 1, 1, 1, 2, 2 ] );

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

// Compute the absolute values:
bunary5d( [ x, y ], shapes, abs );
// y => [ [ [ [ [ 1.0, 2.0 ], [ 1.0, 2.0 ] ] ] ] ]

The function accepts the following arguments:

• arrays: array-like object containing one input nested array and one output nested array.
• shapes: array shapes.
• fcn: unary 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 abs = require( '@stdlib/math-base-special-abs' );
var bunary5d = require( '@stdlib/array-base-broadcasted-unary5d' );

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

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

var y = zeros5d( shapes[ 1 ] );
console.log( y );

bunary5d( [ x, y ], shapes, abs );
console.log( y );
