eval() [1/2]

template<typename T >

virtual void eval ( const std::vector< idx_t > &  rowidxs, const std::vector< idx_t > &  colidxs, value_t *  matrix  ) const

inlinevirtual

return matrix coefficient for index positions defined by tau and sigma, which may be not be consecutively numbered

Implements TCoeffFn< T >.

eval() [2/2]

template<typename T >

virtual void eval ( const TIndexSet &  rowis, const TIndexSet &  colis, value_t *  matrix  ) const

inlinevirtual

return τ x σ subblock of real valued matrix as dense matrix block in column major format

Reimplemented from TCoeffFn< T >.
