-The package is designed to compute a few eigenvalues and corresponding 
-eigenvectors of a general n by n matrix A. It is most appropriate for large 
-sparse or structured matrices A where structured means that a matrix-vector 
-product w <- Av requires order n rather than the usual order n2 floating point
-operations. This software is based upon an algorithmic variant of the Arnoldi
-process called the Implicitly Restarted Arnoldi Method (IRAM). When the matrix
-A is symmetric it reduces to a variant of the Lanczos process called the 
-Implicitly Restarted Lanczos Method (IRLM). These variants may be viewed as a
-synthesis of the Arnoldi/Lanczos process with the Implicitly Shifted QR
-technique that is suitable for large scale problems. For many standard 
-problems, a matrix factorization is not required. Only the action of the matrix
-on a vector is needed.
-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.
