xarray.Dataset.differentiate¶
-
Dataset.
differentiate
(coord, edge_order=1, datetime_unit=None)¶ Differentiate with the second order accurate central differences.
Note
This feature is limited to simple cartesian geometry, i.e. coord must be one dimensional.
Parameters: - coord: str
The coordinate to be used to compute the gradient.
- edge_order: 1 or 2. Default 1
N-th order accurate differences at the boundaries.
- datetime_unit: None or any of {‘Y’, ‘M’, ‘W’, ‘D’, ‘h’, ‘m’, ‘s’, ‘ms’,
‘us’, ‘ns’, ‘ps’, ‘fs’, ‘as’} Unit to compute gradient. Only valid for datetime coordinate.
Returns: - differentiated: Dataset
