    About stdlib...
  </summary>
  <p>We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.</p>
  <p>The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.</p>
  <p>When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.</p>
  <p>To join us in bringing numerical computing to the web, get started by checking us out on <a href="https://github.com/stdlib-js/stdlib">GitHub</a>, and please consider <a href="https://opencollective.com/stdlib">financially supporting stdlib</a>. We greatly appreciate your continued support!</p>

## Usage

```javascript
var toFlippedlr = require( '@stdlib/ndarray-base-to-flippedlr' );
```

#### toFlippedlr( x )

Returns a new ndarray where the order of elements along the last dimension of an input ndarray 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 = toFlippedlr( x );
// returns <ndarray>

sh = y.shape;
// returns [ 3, 2 ]

arr = ndarray2array( y );
// returns [ [ 2.0, 1.0 ], [ 4.0, 3.0 ], [ 6.0, 5.0 ] ]
```

The function accepts the following arguments:

-   **x**: input ndarray.

## Notes

-   If provided a zero-dimensional ndarray, as the ndarray has no dimensions to reverse, the function simply returns a copy of the input ndarray.

## 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 toFlippedlr = require( '@stdlib/ndarray-base-to-flippedlr' );

// 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 last dimension:
var y = toFlippedlr( x );
// returns <ndarray>

var a = ndarray2array( y );
console.log( a );
// => [ [ [ 1, 0 ], [ 3, 2 ], [ 5, 4 ], [ 7, 6 ] ], [ [ 9, 8 ], [ 11, 10 ], [ 13, 12 ], [ 15, 14 ] ] ]
