Must be of dimension mesh.rank + target_rank. Incompatible with target_shape target_shape: list of int, optional Shape of the target space. Incompatible with data is_real: bool Is the Green function real valued ? If true, and target_shape is set, the data will be real. No effect with the parameter data. indices: GfIndices or list of str or list of list of str, Optional Optional string indices for the target space, to allow e.g g['eg', 'eg'] list of list of str: the list of indices for each dimension. list of str: all indices are assumed to be the same for all dimensions. name: str The name of the Green function.
