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.
