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.
