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.

this package contains the debugging symbols for libarpack and libparpack.
