FUNCTION PROTOTYPE

9       void c_nngetslopes(int, int, float *, int *);
10

SYNOPSIS

12       c_nngetslopes (row, column, slope, ier);
13

DESCRIPTION

15       row         A subscript indexing the first dimensioned variable in the
16                   2D grid array returned from the most recent call to
17                   c_natgrids.
18
19       column      A subscript indexing the second dimensioned variable in the
20                   2D grid array returned from the most recent call to
21                   c_natgrids.
22
23       slope       *slope is the slope at the grid point z[i,j], where z is
24                   the output grid in the most recent call to c_natgrids.
25
26       ier         An error value. If *ier is 0, then no errors were detected.
27                   If *ier is non-zero, then refer to the man page for
28                   natgrid_errors for details.
