SlepcArbitrarySelectionFn#

A prototype of an arbitrary selection function that would be passed to EPSSetArbitrarySelection() and analogue functions in other solver types

Synopsis#

PETSC_EXTERN_TYPEDEF typedef PetscErrorCode SlepcArbitrarySelectionFn(PetscScalar er,PetscScalar ei,Vec xr,Vec xi,PetscScalar *rr,PetscScalar *ri,void *ctx);

Calling Sequence#

  • er - real part of the current eigenvalue approximation

  • ei - imaginary part of the current eigenvalue approximation

  • xr - real part of the current eigenvector approximation

  • xi - imaginary part of the current eigenvector approximation

  • rr - result of evaluation (real part)

  • ri - result of evaluation (imaginary part)

  • ctx - [optional] user-defined context for private data for the arbitrary selection routine (may be NULL)
