EPSSetConvergenceTestFunction#

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

Synopsis#

#include "slepceps.h" 
PetscErrorCode EPSSetConvergenceTestFunction(EPS eps,EPSConvergenceTestFn *func,void *ctx,PetscCtxDestroyFn *destroy)

Logically Collective

Input Parameters#

  • eps - eigensolver context obtained from EPSCreate()

  • func - convergence test function, see EPSConvergenceTestFn 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.
