flipud2d

Reverse the order of elements along the first dimension of a two-dimensional nested input array.

Installation

npm install @stdlib/array-base-flipud2d

Usage

var flipud2d = require( '@stdlib/array-base-flipud2d' );

flipud2d( x )

Reverses the order of elements along the first dimension of a two-dimensional nested input array.

var out = flipud2d( [ [ 1, 2 ], [ 3, 4 ] ] );
// returns [ [ 3, 4 ], [ 1, 2 ] ]

Examples

var discreteUniform = require( '@stdlib/random-base-discrete-uniform' ).factory;
var filled2dBy = require( '@stdlib/array-base-filled2d-by' );
var flipud2d = require( '@stdlib/array-base-flipud2d' );

var x = filled2dBy( [ 3, 3 ], discreteUniform( -50, 50 ) );
console.log( x );

var y = flipud2d( x );
console.log( y );

Notice

This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
