#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 PETSC_NULL, it turns off monitoring) | |
mctx | - [optional] context for private data for the monitor routine (use PETSC_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_draw | - sets line graph monitor for the first unconverged approximate singular value | |
-svd_monitor_draw_all | - sets line graph monitor for all unconverged approximate singular value | |
-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. |
