class slepc4py.SLEPc.SVD.Type

Bases: object

SVD type.

Native singular value solvers.

• CROSS: Eigenproblem with the cross-product matrix.

• CYCLIC: Eigenproblem with the cyclic matrix.

• LANCZOS: Explicitly restarted Lanczos.

• TRLANCZOS: Thick-restart Lanczos.

• RANDOMIZED: Iterative RSVD for low-rank matrices.

Wrappers to external SVD solvers (should be enabled during installation of SLEPc).

• LAPACK: Sequential dense SVD solver.

• SCALAPACK: Parallel dense SVD solver.

• KSVD: Parallel dense SVD solver.

• ELEMENTAL: Parallel dense SVD solver.

• PRIMME: Iterative SVD solvers of Davidson type.
