Synopsis

CALL NNGETSLOPED (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 NATGRIDD.
J
(Integer, Input) - A subscript indexing the second dimensioned variable in the output grid of the most recent call to NATGRIDD.
SLOPE
(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.
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.
