PetscErrorCode STFilterGetThreshold(ST st,PetscReal *gamma)
Not Collective
Input Parameter#
st - the spectral transformation context
Output Parameter#
gamma - the threshold value
Note#
An eigenvalue \(\lambda\) is considered to be inside the wanted interval if \(|p(\lambda)|\geq\gamma\), and outside otherwise.
