+## Usage
+
+```javascript
+var ternary5d = require( '@stdlib/array/base/ternary5d' );
+```
+
+#### ternary5d( arrays, shape, fcn )
+
+Applies a ternary callback to elements in three five-dimensional nested input arrays and assigns results to elements in a five-dimensional nested output array.
+
+```javascript
+var zeros5d = require( '@stdlib/array/base/zeros5d' );
+
+function add( x, y, z ) {
+    return x + y + z;
+}
+
+var x = [ [ [ [ [ 1.0, 2.0 ], [ 3.0, 4.0 ] ] ] ] ];
+var out = zeros5d( [ 1, 1, 1, 2, 2 ] );
+
+var shape = [ 1, 1, 1, 2, 2 ];
+
+ternary5d( [ x, x, x, out ], shape, add );
+// out => [ [ [ [ [ 3.0, 6.0 ], [ 9.0, 12.0 ] ] ] ] ]
+```
+
+The function accepts the following arguments:
+
+-   **arrays**: array-like object containing three input nested arrays and one output nested array.
+-   **shape**: array shape.
+-   **fcn**: ternary function to apply.
+

+## Notes
+
+-   The function assumes that the input and output arrays have the same shape.
