Abstract
The singular value decomposition has a number of applications in digital
signal processing. However, the the decomposition must be computed from a
matrix consisting of both signal and noise. It is therefore important to
be able to assess the effects of the noise on the singular values and
singular vectors\,---\,a problem in classical perturbation theory. In
this paper we survey the perturbation theory of the singular value
decomposition.
