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 on SVD

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 (use PETSC_DECIDE to compute an educated guess based on basis and matrix sizes)

Notes

Pass 0 to retain the previous value of any parameter.
