## Usage
34+
35+
```javascript
36+
var bquinary2d = require( '@stdlib/array/base/broadcasted-quinary2d' );
37+
```
38+
39+
#### bquinary2d( arrays, shapes, fcn )
40+
41+
Applies a quinary callback to elements in four [broadcasted][@stdlib/array/base/broadcast-array] nested input arrays and assigns results to elements in a two-dimensional nested output array.
42+
43+
```javascript
44+
var zeros2d = require( '@stdlib/array/base/zeros2d' );
45+
46+
function add( x, y, z, w, v ) {
47+
return x + y + z + w + v;
48+
}
49+
50+
var x = [ [ 1.0, 2.0 ] ];
51+
var y = [ [ 3.0 ], [ 4.0 ] ];
52+
var z = [ [ 5.0 ] ];
53+
var w = [ [ 2.0 ] ];
54+
var v = [ [ 1.0 ] ];
55+
var out = zeros2d( [ 2, 2 ] );
56+
57+
var shapes = [
58+
[ 1, 2 ],
59+
[ 2, 1 ],
60+
[ 1, 1 ],
61+
[ 1, 1 ],
62+
[ 1, 1 ],
63+
[ 2, 2 ]
64+
];
65+
66+
bquinary2d( [ x, y, z, w, v, out ], shapes, add );
67+
// out => [ [ 12.0, 13.0 ], [ 13.0, 14.0 ] ]
68+
```
69+
70+
The function accepts the following arguments:
71+
72+
- **arrays**: array-like object containing five input nested arrays and one output nested array.
73+
- **shapes**: array shapes.
74+
- **fcn**: quinary function to apply.
