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().
