DSHSVDSetReorthogonalize
Sets the reorthogonalization of the left vectors in a DSHSVD.
Synopsis
#include "slepcds.h"
PetscErrorCode DSHSVDSetReorthogonalize(DS ds,PetscBool reorth)
Logically Collective
Input Parameters
| ds | - the direct solver context
|
| reorth | - the reorthogonalization flag
|
Options Database Key
| -ds_hsvd_reorthog <bool> | - sets the reorthogonalization flag
|
Note
The computed left vectors (U) should be orthogonal with respect to the signature (D).
But it may be necessary to enforce this with a final reorthogonalization step (omitted
by default).
