Data Fields
double	aux
	This auxiliary value may be useful to the application but is not used internally. More...

int	clipping
	0: Extrapolate with edge value, 1: zero outside range. More...

CsplinePar *	csp
	Cubic spline parameters (scheme 3 and 4 only), need one-time initialisation. More...

double	dx

double	dxi
	Step size in x and inverse of it, for equidistant only. More...

double	dy

double	dyi
	Step size in y and inverse of it, for equidistant only (2-D). More...

int	equidistant
	Equidistant support points make life much easier (bit 0: x, bit 1: y). More...

char *	fname
	Name of the file from which the table was loaded (includes all options). More...

int	logs

int	ndim
	1 or 2 dimension(s), for the independent variable(s) that is. More...

size_t	nx

size_t	ny
	No. More...

char *	options
	Options used in option parameter or NULL pointer. More...

int	remapped
	If user code remaps x, y, and/or z values w.r.t. More...

int	scheme
	Requested interpolation scheme (0: nearest, 1: linear, 2: quadratic, 3: natural cubic spline, 4: clampled cubic spline). More...

int	use_count
	Indicates how often a table is in use, but not safe enough to make it a smart pointer. More...

double *	x
	Supporting points in x.

int	xlog

double	xmax
	Range covered in x.

double	xmin

double	xrise
	+1 if x values are in ascending order; -1 for descending

double *	y
	Supporting points in y (if ndim=2 and ny>1)

int	ylog

double	ymax
	Range covered in y (if ndim=2)

double	ymin

double	yrise
	+1 if y values are in ascending order; -1 for descending

double *	z
	Table values (size nx for 1-dim or nx*ny for 2-dim)

int	zlog
	Log applied to any x/y axis, to x axis, y axis, z axis?

double	zmax
	Range covered in result values.

double	zmin

double *	zxmax
	Optional max. More...

double *	zxmin
	Optional min. More...

int	zxreq
	Flag activated when options indicate that a set of zxmax values should be provided. More...
