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 - the nonlinear eigensolver context

  • 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 convergence context, as set by NEPSetConvergenceTestFunction()
