Return a read-only view of an input ndarray rotated
180degrees in a specified plane.
var rot180 = require( '@stdlib/ndarray/rot180' );Returns a read-only view of an input ndarray rotated 180 degrees in a specified plane.
var array = require( '@stdlib/ndarray/array' );
var x = array( [ [ 1.0, 2.0 ], [ 3.0, 4.0 ] ] );
// returns <ndarray>[ [ 1.0, 2.0 ], [ 3.0, 4.0 ] ]
var y = rot180( x );
// returns <ndarray>[ [ 4.0, 3.0 ], [ 2.0, 1.0 ] ]The function accepts the following arguments:
- x: input
ndarray. - options: function options.
The function accepts the following options:
- dims: dimension indices defining the plane of rotation. Must contain exactly two unique dimension indices. If a dimension index is provided as an integer less than zero, the dimension index is resolved relative to the last dimension, with the last dimension corresponding to the value
-1. Default:[-2, -1].
- Each provided dimension index must reside on the interval
[-ndims, ndims-1].
