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.
