Classes
struct	mundy::L2Residual
	res = ||r||_2 (absolute). The classic linear-solve convergence measure. More...
struct	mundy::RelativeL2Residual
	res = ||r||_2 / ||b||_2 (relative to the right-hand side). Scale-independent, unlike L2Residual. More...
struct	mundy::LinfResidual
	res = ||r||_inf (max absolute residual entry), via Backend::reduce_max. More...
struct	mundy::LinfNormProjectedGradientResidual
	res = ||proj_grad(x)||_inf, the max absolute projected gradient entry (Eq 2.2 of Dai & Fletcher 2005). Only defined for a non-negativity lower bound. More...
struct	mundy::LinfNormProjectedDiffResidual
	res = ||x - proj(x - h grad)||_inf / h for a small step h (line 17 / Eq 25 of Mazhar 2015). Works for any ValidConvexSpace. More...
