+
+Applies a quinary callback to elements in five [broadcasted][@stdlib/array/base/broadcast-array] input arrays and assigns results to elements in a four-dimensional nested output array.
+
+```javascript
+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 ] );
+

+    [ 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.
