- Basis.make_subbasis(argument, *, metric=None, name=None, orthonormal=False)[source]
Make a new basis with coefficients or indices in reference to the current basis.
- Parameters
argument (BasisArgument) – Sequence, slice, or array defining the sub-basis with respect to the parent basis.
metric (np.ndarray | None) – Metric of the sub-basis. Default: None.
name (str | None) – Name of sub-basis. Default: None.
orthonormal (bool) – True if the sub-basis is orthonormal. Default: False.
- Returns
Sub-basis of parent.
