Small Eigenvalues
SchurCheb is a MPIbased C++ research code for computing partial
spectral factorizations of matrix pencils via Chebyshev
approximation. This is a distributedmemory package for
computing all the eigenvalues (and corresponding eigenvectors)
of a large, sparse, real symmetric positive definite matrix
pencil that lie within a target interval. The algorithm is
purely algebraic.
