c_nngetslopes - retrieve the slope at a specified coordinate.
FUNCTION PROTOTYPEvoid c_nngetslopes(int, int, float *, int *);
SYNOPSISc_nngetslopes (row, column, slope, ier);
- A subscript indexing the first dimensioned variable in the 2D grid array returned from the most recent call to c_natgrids.
- A subscript indexing the second dimensioned variable in the 2D grid array returned from the most recent call to c_natgrids.
- *slope is the slope at the grid point z[i,j], where z is the output grid in the most recent call to c_natgrids.
- 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.
USAGEThis 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.
