NAME
c_nnpnts - interpolate at a single point

FUNCTION PROTOTYPE
void c_nnpnts(float, float, float *);

SYNOPSIS
void c_nnpntinits (x, y, z);

DESCRIPTION

x   The X coordinate of the point where interpolation is desired.

y   The Y coordinate of the point where interpolation is desired.

z   *z is the interpolated functional value at the point (X,Y).

USAGE
This function is invoked when you want to interpolate at an individal point. c_nnpntinits must be called prior to calling c_nnpnts. c_nnpntend must be called to terminate single point mode.
