NAME

6       c_nnpntd - interpolate at a single point
7

FUNCTION PROTOTYPE

9       void c_nnpntd(double, double, double *);
10

SYNOPSIS

12       void c_nnpntd (x, y, z);
13

DESCRIPTION

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

USAGE

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

ACCESS

29       To use c_nnpntd, load the NCAR Graphics library ngmath.
