Which preconditioner to use to ensure generic rank profile.
NO_PRECONDITIONER - Do not use any preconditioner BUTTERFLY - Use a butterfly network, see Butterfly SPARSE - Use a sparse preconditioner, c.f. (Mulders 2000) TOEPLITZ - Use a Toeplitz preconditioner, c.f. (Kaltofen and Saunders 1991) SYMMETRIZE - Use A^T A (Lanczos only) PARTIAL_DIAGONAL - Use AD, where D is a random nonsingular diagonal matrix (Lanczos only) PARTIAL_DIAGONAL_SYMMETRIZE - Use A^T D A, where D is a random nonsingular diagonal matrix (Lanczos only) FULL_DIAGONAL - Use D_1 A^T D_2 A D_1, where D_1 and D_2 are random nonsingular diagonal matrices (Lanczos only) DENSE (Dixon use)
Other shapes : UNIMOD_UT – unimodular upper triang.
Toeplitz UNIMOD_LT – unimodular lower triang. Toeplitz UNIMOD_UH – unimodular upper triang. Hankel UNIMOD_LH – unimodular lower triang. Hankel
