# 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.
