NAME

       c_dsgrid2s - primary single precision C entry for 2D gridding

FUNCTION PROTOTYPE

       float *c_dsgrid2s(int, float [], float [], float [],
                         int, int, float [], float [], int *);

SYNOPSIS

       float *c_dsgrid2s(int n, float x[], float y[], float z[],
                         int nx, int ny, float xo[], float yo[], 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 of size n containing the functional values of the input data points.
                   That is, z[m] is the value of the input function  at  coordinate  (x[m],y[m]),
                   for 0 <= m < n.

       nx          The number of X values in the output grid.

       ny          The number of Y values in the output grid.

       xo          An  array of size nx containing the X coordinates of the output data grid. The
                   values in xo must be increasing, but need not be equally spaced.

       yo          An array of size ny containing the y coordinates of the output data grid.  The
                   values in yo must be increasing, but need not be equally spaced.

       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

       c_dsgrid2s returns a pointer to a linear array of  data  that  is  the  interpolated  grid
       stored in row-major order. That is, if out is declared as

         float *out;

       and we set:

         out = c_dsgrid2s(n, x, y, z, nx, ny, xo, yo, ier);

       then  out[i*ny+j] is the interpolated function value at coordinate point (xo[i],yo[j]) for
       0 <= i < nx and 0 <= j < ny. The space for out is allocated internal to c_dsgrid2s and  is
       nx*ny floats in size.

ACCESS

       To use c_dsgrid2s, load the NCAR Graphics library ngmath.
