Functions

_computeDerivatives void _computeDerivatives(SplineType kind, F param, SplineBoundaryCondition!F lbc, SplineBoundaryCondition!F rbc)
_computeDerivativesTemp void _computeDerivativesTemp(SplineType kind, F param, SplineBoundaryCondition!F lbc, SplineBoundaryCondition!F rbc, Slice!(F*) temp): Computes derivatives and stores them in _data. _data is assumed to be preinitialized with function values filled in F[2 ^^ N][0].
_values void _values(Slice!(Iterator, N, kind) values): Assigns function values to the internal memory. For internal use.
grid Slice!(RCI!(immutable X)) grid()
gridScopeView immutable(X)[] gridScopeView()
gridShape size_t[N] gridShape()
intervalCount size_t intervalCount()
lightConst Spline lightConst()
lightImmutable Spline lightImmutable()

Static functions

pickDataSubslice auto pickDataSubslice(D data, size_t index): Undocumented in source. Be warned that the author may not have intended to support it.

Templates

opCall template opCall(uint derivative : 2)
opCall template opCall(uint derivative = 0)

Variables

_data Slice!(RCI!(F[2^^N]), N) _data;: Aligned buffer allocated with mir.internal.memory. For internal use.
_grid Repeat!(N, RCI!(immutable X)) _grid;: Grid iterators. For internal use.
derivativeOrder enum uint derivativeOrder;
