6 c_nnpntd - interpolate at a single point
7
9 void c_nnpntd(double, double, double *);
10
12 void c_nnpntd (x, y, z);
13
15 x The X coordinate of the point where interpolation is
16 desired.
17
18 y The Y coordinate of the point where interpolation is
19 desired.
20
21 z *z is the interpolated functional value at the point (X,Y).
22
24 This functino is called when you want to interpolate at an individal
25 point. c_nnpntinitd must be called prior to calling c_nnpntd.
26 c_nnpntendd must be called to terminate single point mode.
27
29 To use c_nnpntd, load the NCAR Graphics library ngmath.
