Understanding svd usage and its necessity in generalized inverse calculation

Which seems to say that a method proposed by Byers and Xu (2008) is as
about as good as, but faster than, svd.
It appears to me work on this traces back to a speedup obtained by
Courrieu, whose method takes about one-half as much time as the svd.
