void c_nnpntd(double, double, double *);
void c_nnpntd (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 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.
To use c_nnpntd, load the NCAR Graphics library ngmath.
natgrid, natgrid_params, c_natgrids, c_nnpntinitd, c_nnpntendd.
