NAME

       c_dspnt2s - Interpolate at a single point (or points) in 2D in single precision

FUNCTION PROTOTYPE

       void c_dspnt2s(int, float [], float [], float [],
                      int, float [], float [], float *, int *);

SYNOPSIS

       void c_dspnt2s (int n, float x[], float y[], float z[],
                       int m, float xo[], float yo[], float zo, int *ier);

DESCRIPTION

       n           The number of input data points.

       x           An array containing the X coordinates of the input data points.

       y           An array containing the Y coordinates of the input data points.

       z           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 0 <= l
                   < n .

       m           The number of output data points (this may be "1").

       xo          An array of dimension m containing the X coordinates of the output data. The
                   values in xo may be in any order.

       yo          An array of dimension m containing the Y coordinates of the output data. The
                   values in xo may be in any order.

       zo          A pointer to a float. Space for m floats is allocated for zo by dspnt2s. zo[i]
                   is the interpolated value at point (xo[i],yo[i]) for 0 <= i < n .

       ier         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.

USAGE

       This function is called when you want to interpolate 2D data at an individual point or
       points.

ACCESS

       To use c_dspnt2s, load the NCAR Graphics library ngmath.
