| pc | - the preconditioner, get the application context with PCShellGetContext() Many br | |
| b | - right-hand-side Many br | |
| x | - current iterate Many br | |
| r | - work space Many br | |
| rtol | - relative tolerance of residual norm to stop at Many br | |
| abstol | - absolute tolerance of residual norm to stop at Many br | |
| dtol | - if residual norm increases by this factor than return Many br | |
| maxits | - number of iterations to run Many br |
Notes: the function MUST return an error code of 0 on success and nonzero on failure. Many br
