hackdorte@20008 1 ARPACK software is capable of solving large scale symmetric, nonsymmetric,
hackdorte@20008 2 and generalized eigenproblems from significant application areas. The
hackdorte@20008 3 software is designed to compute a few (k) eigenvalues with user specified
hackdorte@20008 4 features such as those of largest real part or largest magnitude. Storage
hackdorte@20008 5 requirements are on the order of n*k locations. No auxiliary storage is
hackdorte@20008 6 required. A set of Schur basis vectors for the desired k-dimensional
hackdorte@20008 7 eigen-space is computed which is numerically orthogonal to working precision.
hackdorte@20008 8 Numerically accurate eigenvectors are available on request.
