+## Usage
+
+```javascript
+var unary5dBy = require( '@stdlib/array/base/unary5d-by' );
+```
+
+#### unary5dBy( arrays, shape, fcn, clbk\[, thisArg] )
+
+Applies a unary function to each element retrieved from a five-dimensional nested input array according to a callback function and assigns results to elements in a five-dimensional nested output array.
+
+```javascript
+var abs = require( '@stdlib/math/base/special/abs' );
+
+function accessor( v ) {
+    return v * 2.0;
+}
+
+var x = [ [ [ [ [ -1.0, -2.0 ], [ -3.0, -4.0 ] ] ] ] ];
+var shape = [ 1, 1, 1, 2, 2 ];
+
+unary5dBy( [ x, x ], shape, abs, accessor );
+// x => [ [ [ [ [ 2.0, 4.0 ], [ 6.0, 8.0 ] ] ] ] ]
+```
+
+The function accepts the following arguments:
+
+-   **arrays**: array-like object containing one input nested array and one output nested array.
+-   **shape**: array shape.
+-   **fcn**: unary function to apply to callback return values.
+-   **clbk**: callback function.
+-   **thisArg**: callback function execution context (optional).
+
+The invoked callback function is provided the following arguments:
+
+-   **value**: array element.
+-   **indices**: current array element indices.
+-   **arrays**: input and output arrays.
+
+To set the callback execution context, provide a `thisArg`.
+
+<!-- eslint-disable no-invalid-this -->
+
+```javascript
+var abs = require( '@stdlib/math/base/special/abs' );
+
+function accessor( v ) {
+    this.count += 1;
+    return v * 2.0;
+}
+
+var context = {
+    'count': 0
+};
+
+var x = [ [ [ [ [ -1.0, -2.0 ], [ -3.0, -4.0 ] ] ] ] ];
+var y = [ [ [ [ [ 0.0, 0.0 ], [ 0.0, 0.0 ] ] ] ] ];
+
+var shape = [ 1, 1, 1, 2, 2 ];
+
+unary5dBy( [ x, y ], shape, abs, accessor, context );
+// y => [ [ [ [ [ 2.0, 4.0 ], [ 6.0, 8.0 ] ] ] ] ]
+
+var cnt = context.count;
+// returns 4
+```

+
+## Notes
+
+-   If a provided callback function does not return any value (or equivalently, explicitly returns `undefined`), the value is **ignored**.
+
+    ```javascript
+    var abs = require( '@stdlib/math/base/special/abs' );
+
+    function accessor() {
+        // No-op...
+    }
+
+    var x = [ [ [ [ [ -1.0, -2.0 ], [ -3.0, -4.0 ] ] ] ] ];
+    var y = [ [ [ [ [ 0.0, 0.0 ], [ 0.0, 0.0 ] ] ] ] ];
+
+    var shape = [ 1, 1, 1, 2, 2 ];
+
+    unary5dBy( [ x, y ], shape, abs, accessor );
+    // y => [ [ [ [ [ 0.0, 0.0 ], [ 0.0, 0.0 ] ] ] ] ]
+    ```
+
+-   The function assumes that the input and output arrays have the same shape.

+    Applies a unary function to each element retrieved from a five-dimensional
+    nested input array according to a callback function and assigns results to

+    fcn: Function
+        Unary function to apply to callback return values.
