mir.ndslice.dynamic

This is a submodule of mir.ndslice.

Operators only change strides and lengths of a slice. The range of a slice remains unmodified. All operators return slice as the type of the argument, maybe except slice kind.

Transpose operators
Function Name	Description
transposed	Permutes dimensions. `iota(3, 4, 5, 6, 7).transposed!(4, 0, 1).shape` returns `[7, 3, 4, 5, 6]`.
swapped	Swaps dimensions `iota(3, 4, 5).swapped!(1, 2).shape` returns `[3, 5, 4]`.
everted	Reverses the order of dimensions `iota(3, 4, 5).everted.shape` returns `[5, 4, 3]`.

Iteration operators
Function Name	Description
strided	Multiplies the stride of a selected dimension by a factor. `iota(13, 40).strided!(0, 1)(2, 5).shape` equals to `[7, 8]`.
reversed	Reverses the direction of iteration for selected dimensions. `slice.reversed!0` returns the slice with reversed direction of iteration for top level dimension.
allReversed	Reverses the direction of iteration for all dimensions. `iota(4, 5).allReversed` equals to `20.iota.retro.sliced(4, 5)`.

Other operators
Function Name	Description
rotated	Rotates two selected dimensions by `k*90` degrees. `iota(2, 3).rotated` equals to `[[2, 5], [1, 4], [0, 3]]`.
dropToHypercube	Returns maximal multidimensional cube of a slice.
normalizeStructure	Reverses iteration order for dimensions with negative strides, they become not negative; and sorts dimensions according to the strides, dimensions with larger strides are going first.

Bifacial operators

Some operators are bifacial, i.e. they have two versions: one with template parameters, and another one with function parameters. Versions with template parameters are preferable because they allow compile time checks and can be optimized better.

Bifacial interface of drop, dropBack dropExactly, and dropBackExactly is identical to that of strided.

Bifacial interface of dropOne and dropBackOne is identical to that of reversed.

allReversed Slice!(Iterator, N, Universal) allReversed(Slice!(Iterator, N, kind) _slice): Reverses the direction of iteration for all dimensions.
dropToHypercube Slice!(Iterator, N, kind) dropToHypercube(Slice!(Iterator, N, kind) slice)
Slice!(Iterator, N, Canonical) dropToHypercube(Slice!(Iterator, N) slice): Returns maximal multidimensional cube.
everted auto everted(Slice!(Iterator, N, kind) _slice): Reverses the order of dimensions.
normalizeStructure bool normalizeStructure(Slice!(Iterator, N, kind) slice): Reverses iteration order for dimensions with negative strides, they become not negative; and sorts dimensions according to the strides, dimensions with larger strides are going first.
reversed Slice!(Iterator, N, Universal) reversed(Slice!(Iterator, N, kind) _slice, size_t[M] dimensions)
auto reversed(Slice!(Iterator, N, kind) slice): Reverses the direction of iteration for selected dimensions.
rotated auto rotated(Slice!(Iterator, N, kind) _slice, size_t dimensionA, size_t dimensionB, sizediff_t k)
Slice!(Iterator, 2, Universal) rotated(Slice!(Iterator, 2, kind) slice, sizediff_t k): 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.

swapped auto swapped(Slice!(Iterator, N, kind) _slice, size_t dimensionA, size_t dimensionB)
Slice!(Iterator, 2, Universal) swapped(Slice!(Iterator, 2, kind) slice): Swaps two dimensions.
transposed auto transposed(Slice!(Iterator, N, kind) _slice, size_t[M] dimensions)
Slice!(Iterator, 2, Universal) transposed(Slice!(Iterator, 2, kind) slice): N-dimensional transpose operator. Brings selected dimensions to the first position.

Templates

reversed template reversed(Dimensions...): Reverses the direction of iteration for selected dimensions.
