Abstract

	The eigenvalue problem is one of the most important problems in numerical
linear algebra. Several public domain software libraries are available for
solving it. In this work, a new \petsc-based package is presented, which is
intended to be an easy-to-use yet efficient object-oriented parallel framework
for the solution of standard and generalised eigenproblems, either in real or
complex arithmetic. The main objective is to allow the solution of real world
problems in a straightforward way, especially in the case of large software
projects.
