STSetTransform

Sets a flag to indicate whether the transformed matrices are computed or not.

Synopsis

#include "slepcst.h" 
PetscErrorCode STSetTransform(ST st,PetscBool flg)
Logically Collective on st

Input Parameters

st  - the spectral transformation context
flg  - the boolean flag

Options Database Key

-st_transform <bool>  - Activate/deactivate the computation of matrices.

Notes

This flag is intended for the case of polynomial eigenproblems solved via linearization. If this flag is off (default) the spectral transformation is applied to the linearization (handled by the eigensolver), otherwise it is applied to the original problem.
