Webthis is not the case, but they also note that such matrices are the exception rather than the rule [4]. Other inversion methods tend to produce a matrix that is either a left inverse or a right inverse but not both. A good example is Newton’s method. If one iterates with V(t) = (2I V(t 1)A)V(t 1) then V(t) converges to a left inverse.
