arpack: ARPACK (A F77 library for solving large scale eigenvalue problems) arpack: arpack: ARPACK software is capable of solving large scale symmetric, arpack: nonsymmetric, and generalized eigenproblems from significant arpack: application areas. The software is designed to compute a few (k) arpack: eigenvalues with user specified features such as those of largest arpack: real part or largest magnitude. Storage requirements are on arpack: the order of n*k locations. No auxiliary storage is required. arpack: A set of Schur basis vectors for the desired k-dimensional arpack: eigen-space is computed which is numerically orthogonal to working arpack: precision. Numerically accurate eigenvectors are available arpack: on request. arpack: Packaged by Georgi D. Sotirov
