pure virtual |
Initialize the solver to an iterate, providing a complete state.
The FixedPointIteration contains a certain amount of state.
initialize() gives the user the opportunity to manually set these, although only the current unpreconditioned residual is required.
true (see post-conditions of isInitialize())newstate which directly points to the multivectors in the solver, the data is not copied. Implemented in Belos::FixedPointIter< ScalarType, MV, OP >.
|
pure virtual |
Get the current state of the linear solver.
The data is only valid if isInitialized() == true.
Implemented in Belos::FixedPointIter< ScalarType, MV, OP >.
