Summary:

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