Member Function Documentation

integrate_dx()

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).

integrate_dx_perm()

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.
