Change the state of the DS object.

Synopsis#

#include "slepcds.h" 
PetscErrorCode DSSetState(DS ds,DSStateType state)

Logically Collective

Input Parameters#

ds - the direct solver context
state - the new state

Notes#

The state indicates that the dense system is in an initial state (raw), in an intermediate state (such as tridiagonal, Hessenberg or Hessenberg-triangular), in a condensed state (such as diagonal, Schur or generalized Schur), or in a truncated state.

This function is normally used to return to the raw state when the condensed structure is destroyed.
