> Apply a quinary callback to elements in four [broadcasted][@stdlib/array/base/broadcast-array] nested input arrays and assign results to elements in a three-dimensional nested output array.

## Usage

```javascript
var bquinary3d = require( '@stdlib/array/base/broadcasted-quinary3d' );
```

#### bquinary3d( arrays, shapes, fcn )

Applies a quinary callback to elements in four [broadcasted][@stdlib/array/base/broadcast-array] nested input arrays and assigns results to elements in a three-dimensional nested output array.

```javascript
var zeros3d = require( '@stdlib/array/base/zeros3d' );

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 = zeros3d( [ 2, 2, 2 ] );

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

bquinary3d( [ x, y, z, w, v, out ], shapes, add );
// out => [ [ [ 12.0, 13.0 ], [ 13.0, 14.0 ] ] 3
```

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.

<section class="notes">

## Notes

- The input and output array shapes must be broadcast [compatible][@stdlib/ndarray/base/broadcast-shapes].

## Examples

<!-- eslint no-undef: "error" -->

```javascript
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 bquinary3d = require( '@stdlib/array/base/broadcasted-quinary3d' );

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

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

console.log( z );

var w = filled3dBy( shapes[ 3 ], discreteUniform( -100, 100 ) );
console.log( w );

var v = filled3dBy( shapes[ 4 ], discreteUniform( -100, 100 ) );
console.log( v );

var out = zeros3d( shapes[ 5 ] );
console.log( out );

bquinary3d( [ x, y, z, w, v, out ], shapes, add );
