Detailed Description

A tag for the conjugate gradient Used for supplying solver parameters and for dispatching the solve() function.

Definition at line 47 of file mixed_precision_cg.hpp.

Constructor & Destructor Documentation

viennacl::linalg::mixed_precision_cg_tag::mixed_precision_cg_tag	(	double	tol = `1e-8`,

The constructor.

Parameters

tol	Relative tolerance for the residual (solver quits if \|\|r\|\| < tol * \|\|r_initial\|\|)
max_iterations	The maximum number of iterations
inner_tol	Inner tolerance for the low-precision iterations
