an abstract class representing functions on the 1-sphere
S1Fun is the common interface of all representations of a function defined on the circle, e.g. the distribution of an angle. Deriving classes only have to implement the method eval, everything else - arithmetics, plotting, integration - is inherited from here.
Class Properties
| antipodal | f(x) = f(x + pi) |
| bandwidth | maximum harmonic degree |
Derived Classes
| S1FunHarmonic | Fourier series on the circle |
| S1FunHandle | function given by a function handle |
