Detailed Description

template<class Obj, std::size_t LEN>
class tvmet::CommaInitializer< Obj, LEN >

Initialize classes using a comma separated lists.

The comma operator is called when it appears next to an object of the type the comma is defined for. However, "operator," is not called for function argument lists, only for objects that are out in the open, separated by commas (Thinking C++ Ch.12: Operator comma).

This implementation uses the same technique as described in Todd Veldhuizen Techniques for Scientific C++ chapter 1.11 Comma overloading.

The initializer list is avaible after instanciation of the object, therefore use it like:

 vector3d t;
 t = 1.0, 2.0, 3.0;

It's evaluated to (((t = 1.0), 2.0), 3.0)

For matrizes the initilization is done row wise.

If the comma separted list of values longer then the size of the vector or matrix a compile time error will occour. Otherwise the pending values will be written random into the memory.
