摘要：
The Singular Value Decomposition of the equilibrium matrix makes it possible to answer any question of a static, kinematic, or static/kinematic nature for any structural assembly, within a unified computational framework. The paper introduces this decomposition, relates it to the physical properties of a given assembly, and derives formulae for stresses, displacements, etc. A simple example illustrates the calculations.
