__init__(self, coefficients, basis=None, dimension=None): 

• coefficients: np.ndarray

  the expansion coefficients in the basis

• basis: Iterable[function] | None

  a basis of functions to use (defaults to power series)

evaluate(self, points, **kwargs): 

First we just apply the basis to the gridpoints, then we dot this into the coeffs

• points: Any

• kwargs: Any

• :returns: _
