STCayleySetAntishift
Sets the value of the anti-shift for the Cayley spectral transformation. 
Synopsis
#include "slepcst.h" 
PetscErrorCode STCayleySetAntishift(ST st,PetscScalar nu)
Logically Collective on st
Input Parameters
|  | st | - the spectral transformation context | 
|  | nu | - the anti-shift | 
Options Database Key
|  | -st_cayley_antishift | - Sets the value of the anti-shift | 
Note
In the generalized Cayley transform, the operator can be expressed as
OP = inv(A - sigma B)*(A + nu B). This function sets the value of nu.
Use STSetShift() for setting sigma. The value nu=-sigma is not allowed.
