Detailed Description

Object oriented encapsulation of vectors and matrices.

The aim of the classes Vector and Matrix, instead of the usage of Array<double>, is two-fold. First, these classes encapsulate a large part of the LinAlg functionality and thus make the library object-orientated. Second, these classes enable us to write vector and matrix multiplications in a clean and natural operator notation.
