Classes
struct	Belos::CGIterationState< ScalarType, MV >
	Structure to contain pointers to CGIteration state variables. More...
class	Belos::CGIterationInitFailure
	CGIterationInitFailure is thrown when the CGIteration object is unable to generate an initial iterate in the CGIteration::initialize() routine. More...
class	Belos::CGIterateFailure
	CGIterateFailure is thrown when the CGIteration object is unable to compute the next iterate in the CGIteration::iterate() routine. More...
class	Belos::CGPositiveDefiniteFailure
	CGPositiveDefiniteFailure is thrown when the the CG 'alpha = p^H*A*P' value is less than zero, indicating a breakdown in the computation due to roundoff or a non-positive-definite matrix. More...
class	Belos::CGIterationOrthoFailure
	CGIterationOrthoFailure is thrown when the CGIteration object is unable to compute independent direction vectors in the CGIteration::iterate() routine. More...
class	Belos::CGIterationLAPACKFailure
	CGIterationLAPACKFailure is thrown when a nonzero return value is passed back from an LAPACK routine. More...
