## Usage

```javascript
var reverseDimensions = require( '@stdlib/ndarray/base/reverse-dimensions' );
```

#### reverseDimensions( x, dims, writable )

Returns a view of an input ndarray in which the order of elements along specified dimensions is reversed.

```javascript
var array = require( '@stdlib/ndarray/array' );

var x = array( [ [ 1.0, 2.0 ], [ 3.0, 4.0 ], [ 5.0, 6.0 ] ] );
// returns <ndarray>[ [ 1.0, 2.0 ], [ 3.0, 4.0 ], [ 5.0, 6.0 ] ]

var y = reverseDimensions( x, [ 0, 1 ], false );
// returns <ndarray>[ [ 6.0, 5.0 ], [ 4.0, 3.0 ], [ 2.0, 1.0 ] ]
```

The function accepts the following arguments:

- **x**: input ndarray.
- **dims**: dimension indices along which to reverse elements. If provided an integer less than zero, the dimension index is resolved relative to the last dimension, with the last dimension corresponding to the value `-1`.
- **writable**: boolean indicating whether a returned ndarray should be writable.

## Notes

- 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 reverseDimensions = require( '@stdlib/ndarray/base/reverse-dimensions' );

// Create a linear ndarray buffer:
var buf = zeroTo( 16 );

// Create a three-dimensional ndarray:
var x = array( buf, {
'shape': [ 2, 4, 2 ]
});
// returns <ndarray>[ [ [ 0.0, 1.0 ], [ 2.0, 3.0 ], [ 4.0, 5.0 ], [ 6.0, 7.0 ] ], [ [ 8.0, 9.0 ], [ 10.0, 11.0 ], [ 12.0, 13.0 ], [ 14.0, 15.0 ] ] ]

// Reverse elements across all dimensions:
var y = reverseDimensions( x, [ 0, 1, 2 ], false );
// returns <ndarray>[ [ [ 15.0, 14.0 ], [ 13.0, 12.0 ], [ 11.0, 10.0 ], [ 9.0, 8.0 ] ], [ [ 7.0, 6.0 ], [ 5.0, 4.0 ], [ 3.0, 2.0 ], [ 1.0, 0.0 ] ] ]

console.log( ndarray2array( y ) );
```
