Functions

_computeDerivatives void _computeDerivatives(SplineType kind, F param, SplineBoundaryCondition!F lBoundary, SplineBoundaryCondition!F rBoundary)
_computeDerivativesTemp void _computeDerivativesTemp(SplineType kind, F param, SplineBoundaryCondition!F lBoundary, SplineBoundaryCondition!F rBoundary, 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()
opBinary Spline opBinary(Spline rhs): Note: defined only for 1D splines

Templates

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.
convexity SplineConvexity[N] convexity;
derivativeOrder enum uint derivativeOrder;
