rotated

mir ndslice dynamic

Rotates two selected dimensions by k*90 degrees. The order of dimensions is important. If the slice has two dimensions, the default direction is counterclockwise.

  1. auto rotated(Slice!(Iterator, N, kind) _slice, sizediff_t k)

Examples

import mir.ndslice.slice;
import mir.ndslice.topology: iota;
auto slice = iota(2, 3);

auto a = [[0, 1, 2],
          [3, 4, 5]];

auto b = [[2, 5],
          [1, 4],
          [0, 3]];

auto c = [[5, 4, 3],
          [2, 1, 0]];

auto d = [[3, 0],
          [4, 1],
          [5, 2]];

assert(slice.rotated       ( 4) == a);
assert(slice.rotated!(0, 1)(-4) == a);
assert(slice.rotated (1, 0,  8) == a);

assert(slice.rotated            == b);
assert(slice.rotated!(0, 1)(-3) == b);
assert(slice.rotated (1, 0,  3) == b);

assert(slice.rotated       ( 6) == c);
assert(slice.rotated!(0, 1)( 2) == c);
assert(slice.rotated (0, 1, -2) == c);

assert(slice.rotated       ( 7) == d);
assert(slice.rotated!(0, 1)( 3) == d);
assert(slice.rotated (1, 0,   ) == d);
