NAME¶
c_nngetaspectd - retrieve a double precision aspect at a specified coordinate.
FUNCTION PROTOTYPE¶
void c_nngetaspectd(int, int, double *, int *);
SYNOPSIS¶
c_nngetaspectd (row, column, aspect, ier);
DESCRIPTION¶
- row
- A subscript indexing the first dimensioned variable in the 2D grid array
returned from the most recent call to c_natgridd.
- column
- A subscript indexing the second dimensioned variable in the 2D grid array
returned from the most recent call to c_natgridd.
- aspect
- *aspect is the aspect at the grid point z[i,j], where z is the output grid
in the most recent call to c_natgridd.
- 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.
