PEPSetConvergenceTestFunction

Sets a function to compute the error estimate used in the convergence test.

Synopsis

#include "slepcpep.h" 
PetscErrorCode PEPSetConvergenceTestFunction(PEP pep,PEPConvergenceTestFn *conv,void* ctx,PetscCtxDestroyFn *destroy)
Logically Collective

Input Parameters

pep  - eigensolver context obtained from PEPCreate()
conv  - convergence test function, see PEPConvergenceTestFn for the calling sequence
ctx  - context for private data for the convergence routine (may be NULL)
destroy  - a routine for destroying the context (may be NULL), see PetscCtxDestroyFn for the calling sequence

Note

If the error estimate returned by the convergence test function is less than the tolerance, then the eigenvalue is accepted as converged.
