Title: Various changes to linear algebra.

Added functions, tests and (minimal) doc for Moore-Penrose inverse and null space similarly to those in Matlab. Substituted "one" methods with "eye" as they produce the same output. Added some methods for construction of special matrices.

Regarding the "one" methods, I couldn't see the point in having them and "eye", but maybe I have overlooked something. Talking about one method, what is the idea behind the function method that returns the identity?
