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

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

Implements TCoeffFn< T >.

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

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

Reimplemented in TCBCoeffFn< T >.
