In this paper we consider the Procrustes problem on the manifold of orthogonal Stiefel matrices. Given matrices A ε ℝm×k, B ε ℝm×p, m ≥ p ≥ k, we seek the minimum of ∥A - BQ∥2 for all matrices Q ε ℝp×k, QTQ = Ik×k. We introduce a class of relaxation methods for generating sequences of approximations to a minimizer and offer a geometric interpretation of these methods. Results of numerical experiments illustrating the convergence of the methods are given.
