Function Documentation

◆ locate()

int locate	(	double const *	xx,
		double	x,
		int	n
	)

Given an array xx[0..n-1] , and given a value x , returns a value j such that x is between xx[j] and xx[j+1]. xx must be monotonic, either increasing or decreasing. j=0 or j=n is returned to indicate that x is out of range. adapted from Numerical Recipes in C, 2nd Ed., p. 117.

◆ interpn()

void interpn	(	double *	val,
		double const *	coor,
		double const *	data,
		double const *	axis,
		size_t const *	len,
		int	ndim,
		int	nval
	)

Multidimensional linear interpolation val[0..nval-1] : output values coor[0..ndim-1] : coordinate of the interpolation point data[...] : points to the start position of a multidimensional data table. len[0..ndim-1] : length of each dimension axis[...] : coordinates of each dimesnion is placed sequentially in axis

◆ interp1()

double interp1	(	double	x,
		double const *	data,
		double const *	axis,
		size_t	len
	)

A handy function for one dimensional interpolation x : interpolation point data[0..len-1] : data array axis[0..len-1] : coordinates
