NAME

       DSPNT2S - Interpolate at a single point (or points) in 2D in single precision

SYNOPSIS

       CALL DSPNT2S (N, X, Y, Z, M, XO, YO, ZO, IER)

DESCRIPTION

       N           (Integer, Input) - The number of input data points.

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

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

       Z           (Real,  Input)  -  An array 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,N.

       M           (Integer, Input) - The number of output data points (this may be "1").

       XO          (Real,  Input)  -  An array of dimension M containing the X coordinates of the
                   output data. The values in XO may be in any order.

       YO          (Real, Input) - An array of dimension M containing the Y  coordinates  of  the
                   output data. The values in YO may be in any order.

       ZO          (Real,  Output)  - An array of dimension M containing the interpolated values.
                   ZO(I) is the interpolated value at point (XO(I),YO(I)) for I=1,M.

       IER         (Integer, Output) - An error return value. If IER is returned as  0,  then  no
                   errors  were  detected.  If  IER  is  non-zero, then refer to the man page for
                   dsgrid_errors for details.

USAGE

       This subroutine is called when you want to interpolate at an individual point or points.

ACCESS

       To use DSPNT2S, load the NCAR Graphics library ngmath.
