| 30 | PEPMonitorSet - Sets an ADDITIONAL function to be called at every | ||
| 31 | iteration to monitor the error estimates for each requested eigenpair. | ||
| 32 | |||
| 33 | Logically Collective | ||
| 34 | |||
| 35 | Input Parameters: | ||
| 36 | + pep - the polynomial eigensolver context | ||
| 37 | . monitor - pointer to function (if this is `NULL`, it turns off monitoring), | ||
| 38 | see `PEPMonitorFn` | ||
| 39 | . mctx - [optional] context for private data for the monitor routine | ||
| 40 | (use `NULL` if no context is desired) | ||
| 41 | - monitordestroy - [optional] routine that frees monitor context (may be `NULL`), | ||
| 42 | see `PetscCtxDestroyFn` for the calling sequence | ||
| 43 | |||
| 44 | Options Database Keys: | ||
| 45 | + -pep_monitor - print only the first error estimate | ||
| 46 | . -pep_monitor_all - print error estimates at each iteration | ||
| 47 | . -pep_monitor_conv - print the eigenvalue approximations only when | ||
| 48 | convergence has been reached | ||
| 49 | . -pep_monitor draw::draw_lg - sets line graph monitor for the first unconverged | ||
| 50 | approximate eigenvalue | ||
| 51 | . -pep_monitor_all draw::draw_lg - sets line graph monitor for all unconverged | ||
| 52 | approximate eigenvalues | ||
| 53 | . -pep_monitor_conv draw::draw_lg - sets line graph monitor for convergence history | ||
| 54 | - -pep_monitor_cancel - cancels all monitors that have been hardwired into | ||
| 55 | a code by calls to `PEPMonitorSet()`, but does not cancel | ||
| 56 | those set via the options database. | ||
| 57 | |||
| 58 | Notes: | ||
| 59 | The options database option `-pep_monitor` and related options are the easiest way | ||
| 60 | to turn on `PEP` iteration monitoring. | ||
| 61 | |||
| 62 | `PEPMonitorRegister()` provides a way to associate an options database key with `PEP` | ||
| 63 | monitor function. | ||
| 64 | |||
| 65 | Several different monitoring routines may be set by calling `PEPMonitorSet()` multiple | ||
| 66 | times; all will be called in the order in which they were set. | ||
| 67 | |||
| 68 | Fortran Note: | ||
| 69 | Only a single monitor function can be set for each `PEP` object. | ||
