Detailed Description
template<typename Scalar>
class Hermes::Hermes2DFunction< Scalar >
Generic class for functions of two variables. Typical usage: user creates a descendant: class MyComplexASquaredMinusBSquared : public Hermes2DFunction<std::complex<double> > { /// Constructor. MyComplexASquaredMinusBSquared() : Hermes2DFunction<std::complex<double> >() {} std::complex<double> value(std::complex<double> x, std::complex<double> y) const { return x.real * y.real() - x.imag() * y.imag(); } Hermes::Ord value(Hermes::Ord x, Hermes::Ord y) const { return Hermes::Ord(10); // Just say that this particular function is of polynomial order 10. } .... }
