A 2-d function defined by a series expansion and its coefficients.
A Function1d combines a Basis2d that defines basis functions \(B_{n}(x, y)\) with a flattened vector of associated coefficients \(a_{n}\). The basis defines the order of coefficients. Evaluating the function computes
\[ \sum_{n}^{n \le N} a_{n} B_{n}(x, y) \]
