◆ 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 >.
