@stdlib/array-base-broadcasted-quinary2d v0.1.1

bquinary2d

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

Installation

npm install @stdlib/array-base-broadcasted-quinary2d

Usage

var bquinary2d = require( '@stdlib/array-base-broadcasted-quinary2d' );

bquinary2d( arrays, shapes, fcn )

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

var zeros2d = require( '@stdlib/array-base-zeros2d' );

function add( x, y, z, w, v ) {
    return x + y + z + w + v;
}

var x = [ [ 1.0, 2.0 ] ];
var y = [ [ 3.0 ], [ 4.0 ] ];
var z = [ [ 5.0 ] ];
var w = [ [ 2.0 ] ];
var v = [ [ 1.0 ] ];
var out = zeros2d( [ 2, 2 ] );

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

bquinary2d( [ x, y, z, w, v, out ], shapes, add );
// out => [ [ 12.0, 13.0 ], [ 13.0, 14.0 ] ]

The function accepts the following arguments:

• arrays: array-like object containing five input nested arrays and one output nested array.
• shapes: array shapes.
• fcn: quinary 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 filled2dBy = require( '@stdlib/array-base-filled2d-by' );
var zeros2d = require( '@stdlib/array-base-zeros2d' );
var bquinary2d = require( '@stdlib/array-base-broadcasted-quinary2d' );

function add( x, y, z, w, v ) {
    return x + y + z + w + v;
}

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

var x = filled2dBy( shapes[ 0 ], discreteUniform( -100, 100 ) );
console.log( x );

var y = filled2dBy( shapes[ 1 ], discreteUniform( -100, 100 ) );
console.log( y );

var z = filled2dBy( shapes[ 2 ], discreteUniform( -100, 100 ) );
console.log( z );

var w = filled2dBy( shapes[ 3 ], discreteUniform( -100, 100 ) );
console.log( w );

var v = filled2dBy( shapes[ 4 ], discreteUniform( -100, 100 ) );
console.log( v );

var out = zeros2d( shapes[ 5 ] );
console.log( out );

bquinary2d( [ x, y, z, w, v, out ], shapes, add );
console.log( out );
