NAME

6       NNPNTS- Interpolate at a single point
7

SYNOPSIS

9       CALL NNPNTS (X, Y, Z)
10

DESCRIPTION

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

USAGE

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

ACCESS

27       To use NNPNTS, load the NCAR Graphics library ngmath.
