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.
