> For spase matrix, CG method is good in a way of iterative learning.
> This can be applied to many applications (MLP, descent gradient search,
> etc..) as a primitive, not even in linear solution.
> Related paper (From Carnegie Mellon, It presents in verry simple way to
> understand everything behind the CG) is as bellow.
