    void   c_css2cd(int, double *, double *, double *, double *, double *);

    c_css2cd(n, rlat, rlon, x, y, z);

n

The number of input lat/lon coordinates.

rlat

An array containing the latitudes of the input coordinates, in degrees.

rlon

An array containing the longitudes of the input coordinates, in degrees.

x

An array containing the X component of the Cartesian  coordinates of the output data. (x[i],y[i],z[i]) is the Cartesian coordinate corresponding to the lat/lon  coordinate (rlat[i],rlon[i]) for i=0 to n-1.

y

An array containing the Y component of the Cartesian  coordinates of the output data. (x[i],y[i],z[i]) is the Cartesian coordinate corresponding to the lat/lon  coordinate (rlat[i],rlon[i]) for i=0 to n-1.

z

An array containing the Z component of the Cartesian  coordinates of the output data. (x[i],y[i],z[i]) is the Cartesian coordinate corresponding to the lat/lon  coordinate (rlat[i],rlon[i]) for i=0 to n-1.

c_css2cd is called to find the equivalent Cartesian coordinates on a unit sphere to specified latitude and longitude coordinates. The coordinate of 0. latitude and 0. longitude is converted to Cartesian coordinate (1.,0.,0.). Latitudes and  longitudes are assumed to be in degrees.  c_css2cd is a double precision version of c_css2c.

c_css2cd does not return a value.

To use c_css2cd, load the NCAR Graphics library ngmath.
