On Stewart's singular value decomposition for partitioned orthogonal matrices

[摘要] A variant of the singular value decomposition for orthogonal matrices due to G. W. Stewart is discussed. It is shown to be useful in the analysis of (a) the total least squares problem, (b) the Golub-Klema-Stewart subset selection algorithm, and (c) the algebraic Riccati equation.
