operators.nodal_value(x, center=None, rbf=None, monomial=None)

Computes the rbf or polynomial value at position x

Args: x (Float[Array, “dim”]): The position at which to evaluate the rbf or polynomial center (Float[Array, “dim”]): The centroid of the RBF if used. (Currently mandadatory, despite the signature.) rbf (callable): The rbf to use. (Currently mandadatory, despite the signature.) monomial (callable): The monomial to use. (Currently mandadatory, despite the signature.)

Returns: float: The value of the rbf or polynomial at x
