DSSetState

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.
