FUNCTION PROTOTYPE

10       void c_nngetsloped(int, int, double *, int *);
11

SYNOPSIS

13       c_nngetsloped (row, column, slope, ier);
14

DESCRIPTION

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