{{alias}}( x, dims, k, writable ) Rotates an ndarray 90 degrees in a specified plane. If `k > 0`, the function rotates the plane from the first specified dimension toward the second specified dimension. This means that, for a two- dimensional ndarray and `dims = [0, 1]`, the function rotates the plane counterclockwise. If `k < 0`, the function rotates the plane from the second specified dimension toward the first specified dimension. This means that, for a two- dimensional ndarray and `dims = [0, 1]`, the function rotates the plane clockwise. Each provided dimension index must reside on the interval [-ndims, ndims-1]. The returned ndarray is always a *view* of the input ndarray. Accordingly, writing to the original ndarray will mutate the returned ndarray and vice versa. Parameters ---------- x: ndarray Input array. dims: ArrayLikeObject Dimension indices defining the plane of rotation. Must contain exactly two unique dimension indices. If less than zero, an index is resolved relative to the last dimension, with the last dimension corresponding to the value `-1`. k: integer Number of times to rotate by 90 degrees. writable: boolean Boolean indicating whether a returned ndarray should be writable. This parameter only applies to ndarray constructors which support read-only instances. Returns ------- out: ndarray Output array view. Examples -------- > var x = {{alias:@stdlib/ndarray/array}}( [ [ 1, 2 ], [ 3, 4 ] ] ) [ [ 1, 2 ], [ 3, 4 ] ] > var y = {{alias}}( x, [ 0, 1 ], 1, false ) [ [ 2, 4 ], [ 1, 3 ] ] > y = {{alias}}( x, [ 0, 1 ], 2, false ) [ [ 4, 3 ], [ 2, 1 ] ] > y = {{alias}}( x, [ 0, 1 ], 3, false ) [ [ 3, 1 ], [ 4, 2 ] ] See Also --------
