xarray.DataArray.integrate¶
-
DataArray.
integrate
(coord=None, datetime_unit=None, *, dim=None)[source]¶ Integrate along the given coordinate using the trapezoidal rule.
Note
This feature is limited to simple cartesian geometry, i.e. coord must be one dimensional.
- Parameters
coord (hashable, or sequence of hashable) – Coordinate(s) used for the integration.
dim (hashable, or sequence of hashable) – Coordinate(s) used for the integration.
datetime_unit (
{'Y', 'M', 'W', 'D', 'h', 'm', 's', 'ms', 'us', 'ns', 'ps', 'fs', 'as'}
, optional) – Specify the unit if a datetime coordinate is used.
- Returns
integrated (
DataArray

Examples
>>> da = xr.DataArray( ... np.arange(12).reshape(4, 3), ... dims=["x", "y"], ... coords={"x": [0, 0.1, 1.1, 1.2]}, ... ) >>> da <xarray.DataArray (x: 4, y: 3)> array([[ 0, 1, 2], [ 3, 4, 5], [ 6, 7, 8], [ 9, 10, 11]]) Coordinates: * x (x) float64 0.0 0.1 1.1 1.2 Dimensions without coordinates: y >>> >>> da.integrate("x") <xarray.DataArray (y: 3)> array([5.4, 6.6, 7.8]) Dimensions without coordinates: y
