Detailed Description

template<class Numeric, class Axis = UniformAxis>
class npstat::LinInterpolatedTableND< Numeric, Axis >

Template for multilinear interpolation/extrapolation of values provided on a rectangular coordinate grid. "Numeric" is the type stored in the table. "Axis" should be one of GridAxis, UniformAxis, or DualAxis classes or a user-provided class with a similar set of methods.

template<typename Numeric , class Axis >

npstat::LinInterpolatedTableND< Numeric, Axis >::LinInterpolatedTableND	(	const std::vector< Axis > &	axes,
		const std::vector< std::pair< bool, bool > > &	extrapolationType,
		const char *	functionLabel = nullptr
	)

Main constructor for arbitrary-dimensional interpolators.

"axes" are the axes of the rectangular coordinate grid.

In each pair provided by the "extrapolationType" argument, the first element of the pair specifies whether the extrapolation to negative infinity should be linear (if "true") or constant (if "false"). The second element of the pair specifies whether to extrapolate linearly to positive infinity.

"functionLabel" is an arbitrary string which can potentially be used by plotting programs and such.

This method inverts the ratio response. That is, we assume that the table encodes r(x) for some function f(x) = x*r(x). We also assume that the original axis does not represent x directly – instead, axis coordinates are given by g(x) (in practice, g is often the natural log). We will also assume that the new axis is not going to represent f(x) directly – it will be h(f(x)) instead. The functors "invg" and "invh" below must do the inverse: taking the axes coordinates to the actual values of x and f(x). Both "invg" and "invh" must be monotonously increasing functions. The code assumes that x*r(x) -> 0 when x->0 (that is, r(x) is bounded at 0) and it also assumes (but does not check explicitly) that x*r(x) is monotonously increasing with x.

The returned interpolation table encodes the values of x/f(x). Of course, they are just 1/r(x), but the trick is to be able to look them up quickly as a function of h(f(x)). Naturally, this whole operation is meaningful only in case "Numeric" type is either float or double.
