Algorithm 782: Codes for rank-revealing QR factorizations of dense matrices. This article describes a suite of codes as well as associated testing and timing drivers for computing rank-revealing QR (RRQR) factorizations of dense matrices [cf. the authors paper, ibid. 24, No. 2, 226--253 (1998; reviewed above)]. The main contribution is an efficient block algorithm for approximating an RRQR factorization, employing a windowed version of the commonly used pivoting strategy proposed by {it G. Golub} [Numer. Math. 7, 206--216 (1965; Zbl 142.11502)] and improved versions of the RRQR algorithms for triangular matrices originally suggested by {it S. Chandrasekaran} and {it I. C. F. Ipsen} [SIAM J. Matrix Anal. Appl. 15, No. 2, 592--622 (1994; Zbl 796.65030)] and by {it C.-T. Pan} and {it P. T. P. Tang} [SVD and signal processing III, 157--165 (1995; Zbl 826.65032)], respectively. We highlight usage and features of these codes. (Source:
