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.
