class slepc4py.SLEPc.BVSVDMethod

Bases: object

BV methods for computing the SVD.

• REFINE: Based on the SVD of the cross product matrix \(S^H S\),

  with refinement.

• QR: Based on the SVD of the triangular factor of qr(S).

• QR_CAA: Variant of QR intended for use in communication-avoiding

  Arnoldi.
