binarynd

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

Usage

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

binarynd( arrays, shape, fcn )

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

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

var x = [ [ 1.0, 2.0 ], [ 3.0, 4.0 ] ];
var shape = [ 2, 2 ];

binarynd( [ x, x, x ], shape, add );
// x => [ [ 2.0, 4.0 ], [ 6.0, 8.0 ] ]

The function accepts the following arguments:

arrays: array-like object containing two input nested arrays 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 filledndBy = require( '@stdlib/array/base/fillednd-by' );
var zerosnd = require( '@stdlib/array/base/zerosnd' );
var add = require( '@stdlib/math/base/ops/add' );
var binarynd = require( '@stdlib/array/base/binarynd' );

var shape = [ 3, 3 ];

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

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

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

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

shape = [ 3, 3, 3 ];

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

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

z = zerosnd( shape );
console.log( z );

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