Member Function Documentation

virtual void integrate_dx ( const TIndexSet &  is,
const std::vector< T3Point > &  pts,
BLAS::Matrix< value_t > &  matrix 
) const
inlinevirtual

Evaluate $ \int \phi_i(x) D_x \gamma(x, y_{l}) dx$ for i ∈ is and points $ y_{l} $ defined by pts. Store results in matrix at index (i,l).

virtual void integrate_dx_perm ( const std::vector< idx_t > &  idxs,
const std::vector< T3Point > &  pts,
BLAS::Matrix< value_t > &  matrix 
) const
pure virtual

Evaluate $ \int \phi_i(x) D_x \gamma(x, y_{l}) dx$ for i ∈ is and points $ y_{l} $ defined by pts. Indices in idxs are given in external order.
