SVDSetStoppingTestFunction

Sets a function to decide when to stop the outer iteration of the singular value solver.

Synopsis

#include "slepcsvd.h" 
PetscErrorCode SVDSetStoppingTestFunction(SVD svd,SVDStoppingTestFn *stop,void* ctx,PetscErrorCode (*destroy)(void*))
Logically Collective

Input Parameters

svd  - singular value solver context obtained from SVDCreate()
stop  - the stopping test function, see SVDStoppingTestFn for the calling sequence
ctx  - context for private data for the stopping routine (may be NULL)
destroy  - a routine for destroying the context (may be NULL)

Note

Normal usage is to first call the default routine SVDStoppingBasic() and then set reason to SVD_CONVERGED_USER if some user-defined conditions have been met. To let the singular value solver continue iterating, the result must be left as SVD_CONVERGED_ITERATING.
