Abstract
In this paper the Choleski factorization of the mass or the stiffness matrix and its use in reduction of the general free vibration equation to a standard eigenproblem prior to the application of the Lanczos method is described, and their effects on the necessary computing time in determination of the frequencies are discussed.Keywords
