KSP_CONVERGED_RTOL#
norm(r) <= rtolnorm(b) or rtolnorm(b - A*x_0) if KSPConvergedDefaultSetUIRNorm()
was called
See KSPNormType
and KSPSetNormType()
for possible norms that may be used. By default
for left preconditioning it is the 2-norm of the preconditioned residual, and the
2-norm of the residual for right preconditioning
See also KSP_CONVERGED_ATOL
which may apply before this tolerance.
