NEPConvergenceTestFn

A prototype of a NEP convergence test function that would be passed to NEPSetConvergenceTestFunction()

Synopsis

PETSC_EXTERN_TYPEDEF typedef PetscErrorCode(NEPConvergenceTestFn)(NEP nep,PetscScalar eigr,PetscScalar eigi,PetscReal res,PetscReal *errest,void *ctx);

Calling Sequence

nep  - eigensolver context obtained from NEPCreate()
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)
