Class xlifepp::SpectralBasisInt

class SpectralBasisInt : public xlifepp::SpectralBasis

defines global basis functions given by interpolated functions, say TermVectors

Public Functions

SpectralBasisInt(const std::vector<TermVector>&)

constructor from consistent TermVectors (same (sub)space, same unknown)

accessors and shortcuts to properties access to basis

inline virtual const std::vector<TermVector> &basis() const

access to basis

inline virtual SpectralBasisInt *clone() const

clone of current returned as pointer (covariant)

inline virtual complex_t &evaluate(const std::vector<real_t> &p, const Vector<complex_t> &a, complex_t &v) const
