Sets the value of the anti-shift for the Cayley spectral transformation.

Synopsis

#include "slepcst.h" 
PetscErrorCode STCayleySetAntishift(ST st,PetscScalar tau)
Collective on ST

Input Parameters

st - the spectral transformation context
tau - the anti-shift

Options Database Key

-st_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 + tau B). This function sets the value of tau. Use STSetShift() for setting sigma.
