Is there a list of logical rectangular (over-determined) matrices where the pseudoinverse can be solved by a simple algorithm rather than the Mathematica Function PseudoInverse (Moore-Penrose method)?
I seem to recall a page on Wikipedia that listed overdetermined logical (or binary) matrices that have a simple, formula-based solution not requiring Moore-Penrose. I can no longer find that page. Perhaps one of you has a good linear algebra textbook with such examples.
