+## Usage
+
+```javascript
+var flipud = require( '@stdlib/ndarray/base/flipud' );
+```
+
+#### flipud( x, writable )
+
+Returns a view of an input ndarray in which the order of elements along the second-to-last dimension is reversed.
+
+```javascript
+var ndarray = require( '@stdlib/ndarray/ctor' );
+var ndarray2array = require( '@stdlib/ndarray/to-array' );
+
+var buffer = [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ];
+var shape = [ 3, 2 ];
+var strides = [ 2, 1 ];
+var offset = 0;
+
+var x = ndarray( 'generic', buffer, shape, strides, offset, 'row-major' );
+// returns <ndarray>
+
+var sh = x.shape;
+// returns [ 3, 2 ]
+
+var arr = ndarray2array( x );
+// returns [ [ 1.0, 2.0 ], [ 3.0, 4.0 ], [ 5.0, 6.0 ] ]
+
+var y = flipud( x, false );
+// returns <ndarray>
+
+sh = y.shape;
+// returns [ 3, 2 ]
+
+arr = ndarray2array( y );
+// returns [ [ 5.0, 6.0 ], [ 3.0, 4.0 ], [ 1.0, 2.0 ] ]
+```
+
+The function accepts the following arguments:
+
+-   **x**: input ndarray.
+-   **writable**: boolean indicating whether a returned ndarray should be writable.

+
+## Notes
+
+-   If provided a zero-dimensional ndarray, as the ndarray has no dimensions to reverse, the function simply returns a new view of the input ndarray. Similarly, if provided a one-dimensional ndarray, as the ndarray has only one dimension, the function simply returns a new view of the input ndarray.
+-   The `writable` parameter **only** applies to ndarray constructors supporting **read-only** instances.

+## Examples
+
+<!-- eslint no-undef: "error" -->
+
+```javascript
+var array = require( '@stdlib/ndarray/array' );
+var ndarray2array = require( '@stdlib/ndarray/to-array' );
+var zeroTo = require( '@stdlib/array/base/zero-to' );
+var flipud = require( '@stdlib/ndarray/base/flipud' );
+
+// Create a linear ndarray buffer:
+var buf = zeroTo( 16 );
+
+// Create a three-dimensional ndarray:
+var x = array( buf, {
+    'shape': [ 2, 4, 2 ]
+});
+
+// Reverse the order of second-to-last dimension:
+var y = flipud( x, false );
+// returns <ndarray>
+
+var a = ndarray2array( y );
+// returns [ [ [ 6, 7 ], [ 4, 5 ], [ 2, 3 ], [ 0, 1 ] ], [ [ 14, 15 ], [ 12, 13 ], [ 10, 11 ], [ 8, 9 ] ] ]
