+# bquaternary5d
+
+> Apply a quaternary callback to elements in four [broadcasted][@stdlib/array/base/broadcast-array] input arrays and assign results to elements in a five-dimensional nested output array.
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var bquaternary5d = require( '@stdlib/array/base/broadcasted-quaternary5d' );
+```
+
+#### bquaternary5d( arrays, shapes, fcn )
+
+Applies a quaternary callback to elements in four [broadcasted][@stdlib/array/base/broadcast-array] input arrays and assigns results to elements in a five-dimensional nested output array.
+
+```javascript
+var add = require( '@stdlib/math/base/ops/add4' );
+var zeros5d = require( '@stdlib/array/base/zeros5d' );
+
+var x = [ [ 1.0, 2.0 ] ];
+var y = [ [ 3.0 ], [ 4.0 ] ];
+var z = [ [ 5.0 ] ];
+var w = [ [ 2.0 ] ];
+var out = zeros5d( [ 1, 1, 2, 2, 2 ] );
+
+var shapes = [
+ [ 1, 2 ],
+ [ 2, 1 ],
+ [ 1, 1 ],
+ [ 1, 1 ],
+ [ 1, 1, 2, 2, 2 ]
+];
+
+bquaternary5d( [ x, y, z, w, out ], shapes, add );
+// out => [ [ [ [ [ 11.0, 12.0 ], [ 12.0, 13.0 ] ], [ [ 11.0, 12.0 ], [ 12.0, 13.0 ] ] ] ] ]
+```
+
+The function accepts the following arguments:
+
+- **arrays**: array-like object containing four input nested arrays and one output nested array.
+- **shapes**: array shapes.
+- **fcn**: quaternary function to apply.
+
+
+
+
+
+
+
+## Notes
+
+- The input and output array shapes must be broadcast [compatible][@stdlib/ndarray/base/broadcast-shapes].
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var discreteUniform = require( '@stdlib/random/base/discrete-uniform' ).factory;
+var filled5dBy = require( '@stdlib/array/base/filled5d-by' );
+var zeros5d = require( '@stdlib/array/base/zeros5d' );
+var add = require( '@stdlib/math/base/ops/add4' );
+var bquaternary5d = require( '@stdlib/array/base/broadcasted-quaternary5d' );
+
+var shapes = [
+ [ 1, 1, 1, 3, 1 ],
+ [ 1, 3, 1, 1, 1 ],
+ [ 1, 1, 1, 1, 3 ],
+ [ 1, 1, 3, 1, 1 ],
+ [ 1, 3, 3, 3, 3 ]
+];
+
+var x = filled5dBy( shapes[ 0 ], discreteUniform( -100, 100 ) );
+console.log( x );
+
+var y = filled5dBy( shapes[ 1 ], discreteUniform( -100, 100 ) );
+console.log( y );
+
+var z = filled5dBy( shapes[ 2 ], discreteUniform( -100, 100 ) );
+console.log( z );
+
+var w = filled5dBy( shapes[ 3 ], discreteUniform( -100, 100 ) );
+console.log( w );
+
+var out = zeros5d( shapes[ 4 ] );
+console.log( z );
+
+bquaternary5d( [ x, y, z, w, out ], shapes, add );
