A method for eigenvalues of sparse λ‐matrices
Wei Yang · International Journal for Numerical Methods in Engineering · 1983
Abstract The matrix N(λ) whose elements are functions of a parameter λ is called the λ‐matrix. Those values of λ that make the matrix singular are of great interest in many applied fields. An efficient method for those eigenvalues of a λ‐matrix is presented. A simple explicit convergence criterion is given, as well as the algorithm and two numerical examples.
