| Apr 14, 2017 at 22:08 | comment | added | LPM | Anyway thanks, I had completely missed the fact that in reality the matrix is negative SEMIdefinite. Maybe I have to review some basic algebra hehe | |
| Apr 14, 2017 at 21:52 | comment | added | LPM | So, if I have understood correctly, in the case m>=p I am getting those numbers around zero because (since the matrix is now negative semidefinite) there are some null eigenvalues which numerically are not zero but those very small numbers symmetrically distributed around zero? | |
