Abstract

Abstract of the Disclosure:
Characteristics of a coupled system, which consists of a plurality of unit structures coupled together, are analyzed accurately and quickly by providing, between calculating means for calculating transfer function matrices concerning unit structures and coupling means for coupling togethe transfer function matrices according to definitions of coupling, co-ordinate conversion means for converting transfer function matrices into those in the overall system.
