Detailed Description

template<class Titer>
class Seldon::Iteration< Titer >

Class containing parameters for an iterative resolution.

Titer is the precision (float or double), the solved linear system can be real or complex

template<class Titer>
int Seldon::Iteration< Titer >::print_level [protected]

0 -> no display 1 -> displays residual after each 100 iterations 6 -> displays residual after each iteration
