clustering
Definition always_assert.h:6

clustering::all
constexpr Range all()
Sentinel value meaning "take every element of this axis".
Definition ndarray_range.h:26

clustering::Range
Half-open index range with optional positive step for slicing an NDArray axis.
Definition ndarray_range.h:14

clustering::Range::begin
std::size_t begin
Inclusive start index along the target axis.
Definition ndarray_range.h:16

clustering::Range::end
std::size_t end
Exclusive end index; sentinel is clamped to the axis size at slice time.
Definition ndarray_range.h:18

clustering::Range::step
std::ptrdiff_t step
Positive stride in element units; negative values are rejected.
