In modern dynamic analysis of structures, there is often a problem involving the solution of a set of coupled linear ordinary differential equations. The method outlined herein is extremely stable and also very accurate. It is particularly suited to digital computer calculations because the final numerical solution requires only matrix addition and multiplication, and avoids numerical integration. The method also may be applied to semidefinite systems or structures with repeated eigenvalues.
