STResetMatrixState#
Resets the stored state of the matrices in the ST.
Synopsis#
#include "slepcst.h"
PetscErrorCode STResetMatrixState(ST st)
Logically Collective
Input Parameter#
st - the spectral transformation context
Note#
This is useful in solvers where the user matrices are modified during
the computation, as in nonlinear inverse iteration. The effect is that
STGetMatrix() will retrieve the modified matrices as if they were
the matrices originally provided by the user.
