Sets the value of the anti-shift for the Cayley spectral transformation.
Synopsis
#include "slepcst.h"
PetscErrorCode STCayleySetAntishift(ST st,PetscScalar nu)
Logically Collective
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.
