... so that we have R̂x = Q̂∗ b as before. From either interpretation we see that x = R̂−1 Q̂∗ b so that (with this notation) the pseudoinverse is given by A+ = R̂−1 Q̂∗ . This is well-defined since R̂−1 exists because A has full rank. The operations count (using Householder reflectors to compute the QR ...
