In this article, we develop symmetric block successive overrelaxation (S-block-SOR) methods for finding the solution of the rank-deficient least squares problems. We propose an S2-block-SOR and an S3-block-SOR method for solving such problems and the convergence of these two methods is studied. The

In this paper we consider the solution of linear least squares problems min x Ax -b 2 2 where the matrix A ∈ R mΓ—n is rank deficient. Put p = min{m, n}, let Οƒ i , i = 1, 2, . . . , p, denote the singular values of A, and let u i and v i denote the corresponding left and right singular vectors. Then
