Return a view of an input ndarray in which the order of elements along the last dimension is reversed.
npm install @stdlib/ndarray-base-fliplrWe 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. 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. 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. To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

> Return a view of an input ndarray in which the order of elements along the last dimension is reversed.
``bash`
npm install @stdlib/ndarray-base-fliplr
`javascript`
var fliplr = require( '@stdlib/ndarray-base-fliplr' );
#### fliplr( x, writable )
Returns a view of an input ndarray in which the order of elements along the last dimension is reversed.
`javascript
var ndarray = require( '@stdlib/ndarray-ctor' );
var getShape = require( '@stdlib/ndarray-shape' );
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
var sh = getShape( x );
// returns [ 3, 2 ]
var y = fliplr( x, false );
// returns
sh = getShape( y );
// returns [ 3, 2 ]
`
The function accepts the following arguments:
- x: input ndarray.
- writable: boolean indicating whether a returned ndarray should be writable.
- 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.
- The writable parameter only applies to ndarray constructors supporting read-only instances.
`javascript
var array = require( '@stdlib/ndarray-array' );
var ndarray2array = require( '@stdlib/ndarray-to-array' );
var zeroTo = require( '@stdlib/array-base-zero-to' );
var fliplr = require( '@stdlib/ndarray-base-fliplr' );
// 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 = fliplr( x, false );
// returns
var a = ndarray2array( y );
// returns [ [ [ 1, 0 ], [ 3, 2 ], [ 5, 4 ], [ 7, 6 ] ], [ [ 9, 8 ], [ 11, 10 ], [ 13, 12 ], [ 15, 14 ] ] ]
