Summary |
0000495: IMPLEMENTED: automatic diagonal precondtitioner for linear CG and LSQR solvers |

LinCGSolveSparse() and LinLSQRSolveSparse() now use diagonal of the system matrix as preconditioner, which allows to solve systems with badly scaled variables without explicit preconditioning. This preconditioner is active by default. |
