NAME

       c_dsgrid3d - primary double precision C entry for 3D gridding

FUNCTION PROTOTYPE

       double  *c_dsgrid3d(int, double [], double [], double [], double [],
                 int, int, int, double [], double [], double [], int *);

SYNOPSIS

       double  *c_dsgrid3d(int n, double x[], double y[], double z[],
                 double u[], int nx, int ny, int nz, double xo[],
                 double yo[], double 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 Z coordinates of the input data points.

       u           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],z[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.

       nz          The number of Z 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.

       zo          An  array of size nz containing the Z coordinates of the output data grid. The
                   values in zo 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_dsgrid3d  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

         double *out;

       and we set:

         out = *c_dsgrid3d(n, x, y, z, u, nx, ny, nz, xo, yo, zo, ier);

       then out[nz*ny*i + nz*j + k] is  the  interpolated  function  value  at  coordinate  point
       (xo[i],yo[j],zo[k])  for  0  <= i < nx, 0 <= j < ny, and 0 <= k < nz. The space for out is
       allocated internal to c_dsgrid3d and is nx*ny*nz doubles in size.

ACCESS

       To use c_dsgrid3d, load the NCAR Graphics library ngmath.
