2.3.2 List(Comma) Initializer

Allows the user to load a matrix in a natural way using commas. See the example below. This is implemented in two stages. The first stage is the class, ListInit, that has overloaded the comma operator. Secondly, the Matrix class overloads the assignment operator for single elements of type tData. For a complete reference on this technique and many other for that matter, see

Examples:

  Matrix < double, 3, 3 > R;
  R = 0.1,0.2,0.3;
