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).
