CALL NNPNTS (X, Y, Z)
(Real, Input) - The X coordinate of the point where interpolation is desired.
(Real, Input) - The Y coordinate of the point where interpolation is desired.
(Real, Output) - The interpolated functional value at the point (X,Y).
This subroutine is called when you want to interpolate at an individal point. NNPNTINITS must be called prior to calling NNPNTS. NNPNTEND must be called to terminate single point mode.
To use NNPNTS, load the NCAR Graphics library ngmath.
