(
size_t dimension

)
if (

bool opEquals(Slice!(IteratorR, N, rkind) rslice)
bool opEquals(const(T)[] arr)

Parameters

dimension: Dimension to slice.
n size_t: count of elements for the dimension

Return Value

Type: auto

ndslice with length!dimension equal to n.

Examples

import mir.ndslice.topology : iota;
auto sl = iota(3, 4);
assert(sl.selectBack!1(2) == sl[0 .. $, $ - 2 .. $]);

auto a = [1, 2, 3, 4].sliced(2, 2);

assert(a != [1, 2, 3, 4, 5, 6].sliced(2, 3));
assert(a != [[1, 2, 3], [4, 5, 6]]);

assert(a == [1, 2, 3, 4].sliced(2, 2));
assert(a == [[1, 2], [3, 4]]);

assert(a != [9, 2, 3, 4].sliced(2, 2));
assert(a != [[9, 2], [3, 4]]);
