#include "petscksp.h" PetscErrorCode PETSCKSP_DLLEXPORT KSPSetType(KSP ksp, KSPType type)Collective on KSP
|ksp||- the Krylov space context|
|type||- a known method|
Normally, it is best to use the KSPSetFromOptions() command and then set the KSP type from the options database rather than by using this routine. Using the options database provides the user with maximum flexibility in evaluating the many different Krylov methods. The KSPSetType() routine is provided for those situations where it is necessary to set the iterative solver independently of the command line or options database. This might be the case, for example, when the choice of iterative solver changes during the execution of the program, and the user's application is taking responsibility for choosing the appropriate method. In other words, this routine is not for beginners.
