NNGETASPECTD(3NCARG) NCAR GRAPHICS NNGETASPECTD(3NCARG)

NNGETASPECTD - retrieve the double precision aspect at a specified coordinate.

CALL NNGETASPECTD (I,J,ASPECT,IER)

(Integer, Input) - A subscript indexing the first dimensioned variable in the output grid of the most recent call to NATGRIDD.
(Integer, Input) - A subscript indexing the second dimensioned variable in the output grid of the most recent call to NATGRIDD.
(Double precision, Output) - The slope at the grid point Z(I,J), where Z is the output grid in the most recent call to NATGRIDD.
(Integer, Output) - An error return value. If IER is returned as 0, then no errors were detected. If IER is non-zero, then refer to the man page for natgrid_errors for details.

To use NNGETASPECTD, load the NCAR Graphics library ngmath.

natgrid, natgridd, natgrid_params.
