Up: What's New
Previous: Changes in Version
Fixed some bugs.
Implemented the BPX Preconditioned Conjugate Gradient method.
Renamed the module MGSOLV and the program mgtest
in MLSOLV and
because of their true multilevel character.
Improved the estimation of extremal eigenvalues by the Lanczos method.
Accelerated the iterative solvers for zero initial solution
(which arises often within the multigrid algorithm).
Changed the defaults for accuracy in modules RTC and
Extended the structure of type QMatrix,
e.g. by reciprocal values of diagonal elements which are needed in classical
solvers (Jacobi, SOR method) are stored as auxiliary variables.
Implemented the procedure V_SetRndCmp
in module VECTOR which initializes vector
components by random values.
Modified the stopping criterion for GMRES.
Changed the names of some procedures and variables.
