NAME
NNGETSLOPES - retrieve the slope at a specified coordinate.
SYNOPSIS
CALL NNGETSLOPES (I,J,SLOPE,IER)
DESCRIPTION
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.
ACCESS
To use NNGETSLOPES, load the NCAR Graphics library ngmath.
