Detailed Description

template<typename T_val>
class Hpro::TBilinearForm< T_val >

     TBilinearForm is mainly introduced to use BEM bilinear forms
     without ansatz/test space arguments in evaluation, e.g. if
     only a generic pointer to a bilinear form is needed without
     any further knowledge.

◆ eval()

virtual void eval ( const std::vector< idx_t > &  row_ind,
const std::vector< idx_t > &  col_ind,
BLAS::Matrix< value_t > &  values 
) const
pure virtual

evaluate subblock defined by row_ind × col_ind; the indices in row_ind and col_ind can be arbitrary, e.g. must not be contiguous
