60 * Revision 1.1.1.1.2.4 2005/06/29 02:34:57 gross
61 * some changes towards 64 integers in finley
62 *
63 * Revision 1.1.1.1.2.3 2005/03/02 23:35:06 gross
64 * reimplementation of the ILU in Finley. block size>1 still needs some testing
65 *
66 * Revision 1.1.1.1.2.2 2005/02/18 02:27:31 gross
67 * two function that will be used for a reimplementation of the ILU preconditioner
68 *
69 * Revision 1.1.1.1.2.1 2004/11/12 06:58:19 gross
70 * a lot of changes to get the linearPDE class running: most important change is that there is no matrix format exposed to the user anymore. the format is chosen by the Domain according to the solver and symmetry
