| Oct 6, 2009 at 1:04 | comment | added | las3rjock | I mentioned the Moore-Penrose pseudoinverse because I was describing the situation (small m,n) where it should be fairly easy to determine whether or not (A^T A) is invertible. I agree that the notation is sloppy, but it's fairly common in science and engineering literature (which tends to be sloppy about assumptions and notation). | |

Stated the condition for the existence of the Moore-Penrose pseudoinverse
