bquinary4d

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

Usage

var bquinary4d = require( '@stdlib/array/base/broadcasted-quinary4d' );

bquinary4d( arrays, shapes, fcn )

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

var zeros4d = require( '@stdlib/array/base/zeros4d' );

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 = zeros4d( [ 2, 2, 2, 2 ] );

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

bquinary4d( [ x, y, z, w, v, out ], shapes, add );
// out => [ [ [ [ 12.0, 13.0 ], [ 13.0, 14.0 ] ], [ [ 12.0, 13.0 ], [ 13.0, 14.0 ] ] ], [ [ [ 12.0, 13.0 ], [ 13.0, 14.0 ] ], [ [ 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 filled4dBy = require( '@stdlib/array/base/filled4d-by' );
var zeros4d = require( '@stdlib/array/base/zeros4d' );
var bquinary4d = require( '@stdlib/array/base/broadcasted-quinary4d' );

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

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

var x = filled4dBy( shapes[ 0 ], discreteUniform( -100, 100 ) );
console.log( x );

var y = filled4dBy( shapes[ 1 ], discreteUniform( -100, 100 ) );
console.log( y );

var z = filled4dBy( shapes[ 2 ], discreteUniform( -100, 100 ) );
console.log( z );

var w = filled4dBy( shapes[ 3 ], discreteUniform( -100, 100 ) );
console.log( w );

var v = filled4dBy( shapes[ 4 ], discreteUniform( -100, 100 ) );
console.log( v );

var out = zeros4d( shapes[ 5 ] );
console.log( out );

bquinary4d( [ x, y, z, w, v, out ], shapes, add );
console.log( out );
