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.
