## Abstract This paper presents an algorithm for the solution of the inverse problem for a matrix differential equation of the form Aẍ + BαΊ‹ + Cx = 0. In the method use is made of the Taylor formula for a matrix function of many variables. It is shown that the algorithm is always convergent. The pap

Some natural frequencies and their corresponding mass normalized mode shapes of physical structures may be measured by experiment. Since the discretization of the continuous model of the structure reflects only a limited degree of coupling between model elements, the associated mass and stiffness ma

In this paper, a modal identi"cation system that is based on the vector backward autoregressive (VBAR) model has been developed for the identi"cation of natural frequencies, damping ratios and mode shapes of structures from measured output data.

There are many situations in which it would be advantageous to be able to separate a measured response signal into its forcing function and transmission path components. This paper shows how the cepstrum can be used to extract the poles and zeros of the frequency response function (FRF) from a measu
