#include "slepcsvd.h" PetscErrorCode SVDMonitorSet(SVD svd,PetscErrorCode (*monitor)(SVD,PetscInt,PetscInt,PetscReal*,PetscReal*,PetscInt,void*),void *mctx,PetscErrorCode (*monitordestroy)(void**))Collective on svd
| svd | - singular value solver context obtained from SVDCreate() | |
| monitor | - pointer to function (if this is NULL, it turns off monitoring) | |
| mctx | - [optional] context for private data for the monitor routine (use NULL if no context is desired) |
monitor(SVD svd,PetscInt its,PetscInt nconv,PetscReal *sigma,PetscReal *errest,PetscInt nest,void *mctx)
| svd | - singular value solver context obtained from SVDCreate() | |
| its | - iteration number | |
| nconv | - number of converged singular triplets | |
| sigma | - singular values | |
| errest | - relative error estimates for each singular triplet | |
| nest | - number of error estimates | |
| mctx | - optional monitoring context, as set by SVDMonitorSet() |
| -svd_monitor | - print only the first error estimate | |
| -svd_monitor_all | - print error estimates at each iteration | |
| -svd_monitor_conv | - print the singular value approximations only when convergence has been reached | |
| -svd_monitor_lg | - sets line graph monitor for the first unconverged approximate singular value | |
| -svd_monitor_lg_all | - sets line graph monitor for all unconverged approximate singular values | |
| -svd_monitor_cancel | - cancels all monitors that have been hardwired into a code by calls to SVDMonitorSet(), but does not cancel those set via the options database. |
