10
12 NPNTS (Integer, Input) - The number of input data points. (NPNTS
13 > 3).
14
15 X (Real, Input) - An array of dimension NPNTS containing the
16 X coordinates of the input data points.
17
18 Y (Real, Input) - An array of dimension NPNTS containing the
19 Y coordinates of the input data points.
20
21 Z (Real, Input) - An array of dimension NPNTS containing the
22 functional values of the input data points. That is, Z(L)
23 is the value of the input function at coordinate
24 (X(L),Y(L)), for L=1,NPNTS.

27 This subroutine is called when you want to interpolate at individal
28 points. It is an initialization routine that sets up some internal
29 variables and does this initial triangulation. To actually do the
30 interplation, use subroutine NNPNTS. To terminate single point mode,
31 use the subroutine NNPNTEND.
32
34 To use NNPNTINITS, load the NCAR Graphics library ngmath.
