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)
