%description
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
quadratic eigenvalue problems.
