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.
