xarray.DataArray.dot¶
-
DataArray.
dot
(other, dims=None)¶ Perform dot product of two DataArrays along their shared dims.
Equivalent to taking taking tensordot over all shared dims.
Parameters: other : DataArray
The other array with which the dot product is performed.
dims: list of strings, optional
Along which dimensions to be summed over. Default all the common dimensions are summed over.
Returns: result : DataArray
Array resulting from the dot product over all shared dimensions.

Examples
>>> da_vals = np.arange(6 * 5 * 4).reshape((6, 5, 4)) >>> da = DataArray(da_vals, dims=['x', 'y', 'z']) >>> dm_vals = np.arange(4) >>> dm = DataArray(dm_vals, dims=['z'])
>>> dm.dims ('z') >>> da.dims ('x', 'y', 'z')
>>> dot_result = da.dot(dm) >>> dot_result.dims ('x', 'y')
