But a pseudoinverse (a.k.a. Moore-Penrose inverse) is always defined and has a set of interesting attributes and can be calculated through SVD (Single Value Decomposition). What if we have a ::pseudoinverse() method for Matrix object? 109088 1 dschulze 2014-07-18 19:21:18 +0000 (In reply to Adenilson Cavalcanti from comment #0) > It is known fact that not all matrix can have an inverse calculated. > > But a pseudoinverse (a.k.a.

That is a really interesting idea. For the first level I would like to keep a narrow scope and suggest deferring the idea for Level 2. Is that ok with you? 109094 2 a.cavalcanti 2014-07-18 19:54:38 +0000 Level2 it is! :-)
