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.
