SVDSetTolerances
Sets the tolerance and maximum iteration count used by the default SVD convergence testers.
Synopsis
#include "slepcsvd.h"
PetscErrorCode SVDSetTolerances(SVD svd,PetscReal tol,PetscInt maxits)
Logically Collective
Input Parameters
| svd | - the singular value solver context
|
| tol | - the convergence tolerance
|
| maxits | - maximum number of iterations to use
|
Options Database Keys
| -svd_tol <tol> | - Sets the convergence tolerance
|
| -svd_max_it <maxits> | - Sets the maximum number of iterations allowed
|
Note
Use PETSC_CURRENT to retain the current value of any of the parameters.
Use PETSC_DETERMINE for either argument to assign a default value computed
internally (may be different in each solver).
For maxits use PETSC_UMLIMITED to indicate there is no upper bound on this value.
