Classes
class	dg::mat::MCG< ContainerType >
	EXPERIMENTAL Tridiagonalize \(A\) and approximate \(f(A)b \approx R f(\tilde T) e_1\) via CG algorithm. A is self-adjoint in the weights \( W\). More...
class	dg::mat::MCGFuncEigen< Container >
	EXPERIMENTAL Shortcut for \(x \approx f(A) b \) solve via exploiting first a Krylov projection achieved by the M-CG method and a matrix function computation via Eigen-decomposition. More...
