ncl_c_nngetsloped man page
c_nngetsloped — retrieve a double precision slope at a specified coordinate.
void c_nngetsloped(int, int, double *, int *);
c_nngetsloped (row, column, slope, ier);
A subscript indexing the first dimensioned variable in the 2D grid array returned from the most recent call to c_natgridd.
A subscript indexing the second dimensioned variable in the 2D grid array returned from the most recent call to c_natgridd.
*slope is the slope at the grid point z[i,j], where z is the output grid in the most recent call to c_natgridd.
An error value. If *ier is 0, then no errors were detected. If *ier is non-zero, then refer to the man page for natgrid_errors for details.
This routine allows you to retrieve the current value of Natgrid parameters. For a complete list of parameters available in this utility, see the natgrid_params man page.
To use c_nngetsloped, load the NCAR Graphics library ngmath.
