flipud

Return a read-only view of an input ndarray in which the order of elements along the second-to-last dimension is reversed.

Installation

npm install @stdlib/ndarray-flipud

Usage

var flipud = require( '@stdlib/ndarray-flipud' );

flipud( x )

Returns a read-only view of an input ndarray in which the order of elements along the second-to-last dimension is reversed.

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

var x = array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ], {
    'shape': [ 3, 2 ]
});
// returns <ndarray>[ [ 1.0, 2.0 ], [ 3.0, 4.0 ], [ 5.0, 6.0 ] ]

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

Examples

var uniform = require( '@stdlib/random-uniform' );
var ndarray2array = require( '@stdlib/ndarray-to-array' );
var flipud = require( '@stdlib/ndarray-flipud' );

var x = uniform( [ 3, 3, 3 ], -10.0, 10.0 );
console.log( ndarray2array( x ) );

var y = flipud( x );
console.log( ndarray2array( y ) );
