CALL NNGETSLOPES (I,J,SLOPE,IER)
(Integer, Input) - A subscript indexing the first dimensioned variable in the output grid of the most recent call to NATGRIDS.
(Integer, Input) - A subscript indexing the second dimensioned variable in the output grid of the most recent call to NATGRIDS.
(Real, Output) - The slope at the grid point Z(I,J), where Z is the output grid in the most recent call to NATGRIDS.
(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.
