Some Extensions of an Algorithm for Sparse Linear Least Squares Problems

Journal Article · · SIAM Journal on Scientific and Statistical Computing
DOI:https://doi.org/10.1137/0903014· OSTI ID:6787320
In this paper several algorithms are developed which extend the method of George and Heath for sparse linear least squares problems to include rank deficient problems, linear equality constrained problems, and updating of solutions. An application of these methods to the solution of sparse square nonsymmetric linear systems is also presented.
