Computing the transmission zeros of large space structures

The transmission zeros of a large space structure are frequently computed by means of the general-purpose algorithm of Emami-Naeini and Van Dooren (1982). It is shown that careful exploitation of the special form of the equations of motion of structural dynamics leads to an algorithm that is at least 60 times as fast as this when applied to an undamped structure, and 15 times as fast for a lightly damped one.
