weldx.util.xr_matmul#
- weldx.util.xr_matmul(a, b, dims_a, dims_b=None, dims_out=None, trans_a=False, trans_b=False, **apply_kwargs)#
Calculate broadcasted np.matmul(a,b) for xarray objects.
Should work for any size and shape of quadratic matrices contained in a DataArray. Ordering, broadcasting of dimensions should be taken care of by xarray internally. This can be used for both matrix * matrix and matrix * vector operations.
- Parameters:
a – xarray object containing the first matrix
b – xarray object containing the second matrix
dims_a – name and order of dimensions in the first object
dims_b – name and order of dimensions in the second object (if None, use dims_a) (Default value = None)
dims_out – name and order of dimensions in the resulting object (if None, use dims_a unless dims_b has less items than dims_b) (Default value = None)
trans_a – flag if matrix in a should be transposed (Default value = False)
trans_b – flag if matrix in b should be transposed (Default value = False)
**apply_kwargs – additional kwargs passed on to ur.apply_ufunc
- Return type:
