Gets the reason why the SVDSolve() iteration was stopped.
Synopsis#

PetscErrorCode SVDGetConvergedReason(SVD svd,SVDConvergedReason *reason)
Not Collective
Input Parameter#
svd - the singular value solver context
Output Parameter#
reason - negative value indicates diverged, positive value converged, see
SVDConvergedReasonfor the possible values
Options Database Key#
-svd_converged_reason - print reason for convergence/divergence, and number of iterations
Note#
If this routine is called before or doing the SVDSolve() the value of
SVD_CONVERGED_ITERATING is returned.
