## Description

Title of program: EIGVEC Catalogue Id: AARI_v1_0 Nature of problem This package solves the generalized eigenvalue problem Ax = lambdaBx, a problem which arises often, for example, in: physics, mechanics, and chemistry. Here A and B have a global block diagonal form and fine sparse structure as found in two-dimensional problems with a finite element approach. Versions of this program held in the CPC repository in Mendeley Data AARI_v1_0; EIGVEC; 10.1016/0010-4655(82)90045-5 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)
