A method for eigenvalues of sparse lambda-matrices
Wantong Yang · Am. Soc. Mech. Eng., (Pap.); (United States) · 1982
The matrix N(lambda) whose elements are functions of a parameter lambda is called the lambda-matrix. Those values of lambda that make the matrix singular are of great interest in many applied fields. An efficient method for those eigenvalues of a lambda-matrix is presented. A simple explicit convergence criterion is given as well as the algorithm and two numerical examples.
