ncl_c_nngetslopes: retrieve the slope at a specified coordinate.
NAME
c_nngetslopes - retrieve the slope at a specified coordinate.
FUNCTION PROTOTYPE
void c_nngetslopes(int, int, float *, int *);SYNOPSIS
c_nngetslopes (row, column, slope, ier);DESCRIPTION
- row
- A subscript indexing the first dimensioned variable in the 2D grid array returned from the most recent call to c_natgrids.
- column
- A subscript indexing the second dimensioned variable in the 2D grid array returned from the most recent call to c_natgrids.
- slope
- *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.
- ier
- 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.
