The first one uses the SR1 updates to compute the matrix [H.sub.m] = [H.sup.{m}][([H.sup.{m}]).sup.*] in the first step and the S-M formula to compute [H.sup.[dagger].sub.m] in the subsequent step.
Since rank([H.sub.n]) = rank(HH*) = m, the invertibility of [H.sub.n] is guaranteed, so that we are able to apply the S-M formula which relates [H.sup.-1.sub.k] with [H.sup.-1.sub.k-1] , for each k = m + 1, ..., n.
The algorithm is based on the SR1 modifications to compute [H.sub.m] and subsequently the S-M formula to compute [H.sup.[dagger]].
