I

(Integer, Input) - A subscript indexing the first dimensioned variable  in the output grid of the most recent call to NATGRIDS.

J

(Integer, Input) - A subscript indexing the second dimensioned variable  in the output grid of the most recent call to NATGRIDS.

SLOPE

(Real, Output) - The slope at the grid point Z(I,J), where Z is the  output grid in the most recent call to NATGRIDS.

IER

(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 NNGETSLOPES, load the NCAR Graphics library ngmath.
