NAME

       NNPNTINITS- Enter single point mode

SYNOPSIS

       CALL NNPNTINITS (NPNTS, X, Y, Z)

DESCRIPTION

       NPNTS       (Integer, Input) - The number of input data points. (NPNTS > 3).

       X           (Real,  Input)  -  An array of dimension NPNTS containing the X coordinates of
                   the input data points.

       Y           (Real, Input) - An array of dimension NPNTS containing the  Y  coordinates  of
                   the input data points.

       Z           (Real,  Input)  - An array of dimension NPNTS containing the functional values
                   of the input data points. That is, Z(L) is the value of the input function  at
                   coordinate (X(L),Y(L)), for L=1,NPNTS.

USAGE

       This  subroutine  is  called  when  you want to interpolate at individal points.  It is an
       initialization routine that  sets  up  some  internal  variables  and  does  this  initial
       triangulation.   To  actually  do  the  interplation, use subroutine NNPNTS.  To terminate
       single point mode, use the subroutine NNPNTEND.

ACCESS

       To use NNPNTINITS, load the NCAR Graphics library ngmath.
