Description Adenilson Cavalcanti 2014-07-17 19:46:51 UTC 
It is known fact that not all matrix can have an inverse calculated. 

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?

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?

Level2 it is! :-)
