PEPConvergenceTestFn#
A prototype of a PEP convergence test function that would be passed to PEPSetConvergenceTestFunction()
Synopsis#
PETSC_EXTERN_TYPEDEF typedef PetscErrorCode PEPConvergenceTestFn(PEP pep,PetscScalar eigr,PetscScalar eigi,PetscReal res,PetscReal *errest,void *ctx);
Calling Sequence#
pep - eigensolver context obtained from PEPCreate()
eigr - real part of the eigenvalue
eigi - imaginary part of the eigenvalue
res - residual norm associated to the eigenpair
errest - [output] computed error estimate
ctx - [optional] user-defined context for private data for the convergence test routine (may be NULL)
