6 NNPNTS- Interpolate at a single point
7
9 CALL NNPNTS (X, Y, Z)
10
12 X (Real, Input) - The X coordinate of the point where inter‐
13 polation is desired.
14
15 Y (Real, Input) - The Y coordinate of the point where inter‐
16 polation is desired.
17
18 Z (Real, Output) - The interpolated functional value at the
19 point (X,Y).
20
22 This subroutine is called when you want to interpolate at an individal
23 point. NNPNTINITS must be called prior to calling NNPNTS. NNPNTEND
24 must be called to terminate single point mode.
25
27 To use NNPNTS, load the NCAR Graphics library ngmath.
