bunary3d

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

Usage

var bunary3d = require( '@stdlib/array/base/broadcasted-unary3d' );

bunary3d( arrays, shapes, fcn )

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

var zeros3d = require( '@stdlib/array/base/zeros3d' );
var abs = require( '@stdlib/math/base/special/abs' );

var x = [ [ [ -1.0, -2.0 ] ] ];
var y = zeros3d( [ 1, 2, 2 ] );

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

// Compute the absolute values:
bunary3d( [ 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 filled3dBy = require( '@stdlib/array/base/filled3d-by' );
var zeros3d = require( '@stdlib/array/base/zeros3d' );
var abs = require( '@stdlib/math/base/special/abs' );
var bunary3d = require( '@stdlib/array/base/broadcasted-unary3d' );

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

var x = filled3dBy( shapes[ 0 ], discreteUniform( -100, 100 ) );
console.log( x );

var y = zeros3d( shapes[ 1 ] );
console.log( y );

bunary3d( [ x, y ], shapes, abs );
console.log( y );
