NAME

c_nnpntd - interpolate at a single point

FUNCTION PROTOTYPE

void c_nnpntd(double, double, double *);

SYNOPSIS

void c_nnpntd (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 functino is called when you want to interpolate at an individal point. c_nnpntinitd must be called prior to calling c_nnpntd. c_nnpntendd must be called to terminate single point mode.
