Let T denote an operator on a Hilbert space β€’ β€’ , and let f i ∞ i=1 be a frame for the orthogonal complement of the kernel N T . We construct a sequence of operators n of the form n β€’ = n i=1 β€’ g n i f i which converges to the psuedoinverse T † of T in the strong operator topology as n β†’ ∞. The oper
