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 comparisons between the S2-block and the S3-block methods are presented
with some numerical examples.
