NNGETSLOPED – retrieve the double precision slope at a specified coordinate.
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.
Access
To use NNGETSLOPED, load the NCAR Graphics library ngmath.
