STSetShift

Sets the shift associated with the spectral transformation.

Synopsis

#include "slepcst.h" 
PetscErrorCode STSetShift(ST st,PetscScalar shift)
Collective

Input Parameters

st  - the spectral transformation context
shift  - the value of the shift

Notes

In some spectral transformations, changing the shift may have associated a lot of work, for example recomputing a factorization.

This function is normally not directly called by users, since the shift is indirectly set by EPSSetTarget().
