In this paper we investigate the question of convergence for degenerate descent procedures. The results focus attention on the role of a property of symmetric matrices analogous to, but different from, the usual condition number used in numerical linear algebra. The main result is a bound which establishes a specific rate of exponential decay for time varying linear systems with singular A matrices.
