Object-oriented version of the ARPACK package (runtime)
ARPACK++ is an object-oriented version of the ARPACK package. It consists a collection of classes that offers c++ programmers an interface to ARPACK. It preserves the full capability, performance, accuracy and low memory requirements of the FORTRAN package, but takes advantage of the c++ object-oriented programming environment.
ARPACK stands for ARnoldi PACKage and provides standard and generalized eigenvalue solvers for sparse matrices that arises typically from finite element codes. See the corresponding Debian package.
