+#### bquaternary3d( arrays, shapes, fcn )

+
+```javascript
+var add = require( '@stdlib/math/base/ops/add4' );
+var zeros3d = require( '@stdlib/array/base/zeros3d' );
+
+var x = [ [ 1.0, 2.0 ] ];

+The function accepts the following arguments:

+-   **arrays**: array-like object containing four input nested arrays and one output nested array.
+-   **shapes**: array shapes.
