Dear fellows,
during my internship I've stumbled over a problem of analysis. To cut things short some pseudoinverses have to be calculated. For one of them it does not work, s.t. A'*A [itex]\neq[/itex] I.
I just wondered about the requirements to find a pseudoinverse. One of the eigenvalues is zero, but as far as I understand that eigenvalues different than zero are not a requirement.
The matrix under consideration is that one:
A = [1 -1 0; 1 0 -1; 0 -1 1; 0 -1 1];
If anyone could help me that would be really great :).
Cheers and thank you very much in advance,
