SLEPc: Scalable Library for Eigenvalue Problem Computations
===========================================================
SLEPc is a software library for the solution of large scale sparse
eigenvalue problems on parallel computers. It is an extension of PETSc
and can be used for either standard or generalized eigenproblems, with
real or complex arithmetic. It can also be used for computing a
partial SVD of a large, sparse, rectangular matrix, and to solve
nonlinear eigenvalue problems
.. note::
To install ``PETSc``, ``SLEPc``, ``petsc4py``, and ``slepc4py``
(``mpi4py`` is optional but highly recommended) use::
$ pip install numpy mpi4py
$ pip install petsc petsc4py
$ pip install slepc slepc4py
