STSetShift
Sets the shift associated with the spectral transformation.
Synopsis
#include "slepcst.h"
PetscErrorCode STSetShift(ST st,PetscScalar shift)
Collective
Input Parameters
| st | - the spectral transformation context
|
| shift | - the value of the shift
|
Notes
In some spectral transformations, changing the shift may have associated
a lot of work, for example recomputing a factorization.
This function is normally not directly called by users, since the shift is
indirectly set by EPSSetTarget().
