| Abstract: | In this paper, a new construction space, based on sine transform pre-conditioners, is presented. Compared with the old spaces, in the new one the preconditioners is acrossdiagonalized, instead of diagonalizing them. Therefore it provides a wider space for the choice of preconditioners. |
