void c_nnpnts(float, float, float *);
void c_nnpntinits (x, y, z);
The X coordinate of the point where interpolation is desired.
The Y coordinate of the point where interpolation is desired.
*z is the interpolated functional value at the point (X,Y).
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.
To use c_nnpnts, load the NCAR Graphics library ngmath.
