1 ARPACK software is capable of solving large scale symmetric, nonsymmetric,
2 and generalized eigenproblems from significant application areas. The
3 software is designed to compute a few (k) eigenvalues with user specified
4 features such as those of largest real part or largest magnitude. Storage
5 requirements are on the order of n*k locations. No auxiliary storage is
6 required. A set of Schur basis vectors for the desired k-dimensional
7 eigen-space is computed which is numerically orthogonal to working precision.
8 Numerically accurate eigenvectors are available on request.
