In solving large sparse linear least squares problems <italic>A</italic> x &sime; b, several different numeric methods involve computing the same upper triangular factor <italic>R</italic> of <italic>A</italic>. It is of interest to be able to compute the nonzero structure of <italic>R</italic>, given only the structure of <italic>A</italic>. The solution(More)
