Public Functions

inline virtual ~SpectralBasis()

virtual destructor

virtual SpectralBasis *clone() const = 0

virtual copy constructor

inline dimen_t dimFun() const

returns dimension of basis functions

inline number_t dimSpace() const

returns space dimension (=number of basis functions)

inline const GeomDomain *domain() const

returns related domain

virtual real_t &evaluate(const std::vector<real_t>&, const Vector<real_t>&, real_t&) const = 0

evaluate linear combination of spectral functions, say v = sum_k a_k f_k(P) no virtual template !!

virtual void print(std::ostream&) const = 0

print utility

inline StrucType strucType() const

returns structure of returned value

inline ValueType valueType() const

returns type of returned value
