Detailed Description

template<typename FUNCTOR>
class LatBuilder::Kernel::FunctorAdaptor< FUNCTOR >

Generic kernel for functors.

This class allows for polymorphism while inlining the functor calls in the loop that initializes new vectors.

Template Parameters

FUNCTOR

Type of functor.

Member Function Documentation

valuesVector()

template<typename FUNCTOR>

template<LatticeType LR, EmbeddingType L, Compress C, PerLevelOrder P>

RealVector LatBuilder::Kernel::FunctorAdaptor< FUNCTOR >::valuesVector ( const Storage< LR, L, C, P > &  storage ) const

inline

Creates a new vector of kernel values.

The values of the kernel evaluated at sizeParam.numPoints() regular intervals in \([0,1)\) are stored in a linear vector. The intervals are of size 1/sizeParam.numPoints() and the first point is at 0.

Returns

The newly created vector.

The \(i^{\text{th}}\) element \(\omega_i\) is:

• \(\omega(i/n)\) in the case of an ordinary lattice with modulus \(n\).

• \(\omega((\nu_m(\frac{i(z)}{P(z)}))\) in the case of a polynomial lattice of modulus \(P(z)\) ( \( i(z) = \sum a_iz^i\) where \(i =\sum a_i2^i\)).

  Remarks

  Checks that the functor and the compression are compatible, or throws a std::logic_error.
