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