New: The SolverGMRES
now accepts
- an AdditionalData
parameter
- use_default_residual
whose default is
- true
. By setting this flag to false
, the
- stopping criterion of the left-preconditioned GMRes solver is not
- the default preconditioned residual but the normal (unpreconditioned)
- residual and visa versa for the right-preconditioned GMRes
- solver. Due to a performance loss of the solver this flag should
- be set to false
only for debugging/testing purposes.

New: FullMatrix
has a
- function copy_from
, copying from sparse matrices.
- It uses iterators of the sparse matrix classes.

Changed: In an attempt to unify the use of preconditioners a little,
- the function initialize
of classes PreconditionRelaxation
and PreconditionBlock
take an argument of type AdditionalData
, defined in the same class.
- Standard behavior of PreconditionBlock
has been
- changed on this occasion to invert diagonal blocks during initialization.
