template<typename VectorT >

void viennacl::linalg::gmres_solver< VectorT >::set_initial_guess ( VectorT const &  x )

inline

Specifies an initial guess for the iterative solver.

An iterative solver for Ax = b with initial guess x_0 is equivalent to an iterative solver for Ay = b' := b - Ax_0, where x = x_0 + y.

template<typename VectorT >

void viennacl::linalg::gmres_solver< VectorT >::set_monitor ( bool(*)(VectorT const &, numeric_type, void *)  monitor_fun, void *  user_data  )

inline

Sets a monitor function pointer to be called in each iteration. Set to NULL to run without monitor.

The monitor function is called with the current guess for the result as first argument and the current relative residual estimate as second argument. The third argument is a pointer to user-defined data, through which additional information can be passed. This pointer needs to be set with set_monitor_data. If not set, NULL is passed. If the montior function returns true, the solver terminates (either convergence or divergence).

gmres_tag const& viennacl::linalg::gmres_solver< VectorT >::tag ( ) const
