NEPNLEIGSSingularitiesFn#

A prototype of a function that would be passed to NEPNLEIGSSetSingularitiesFunction().

Synopsis#

PETSC_EXTERN_TYPEDEF typedef PetscErrorCode NEPNLEIGSSingularitiesFn(NEP nep,PetscInt *maxnp,PetscScalar *xi,void *ctx);

Calling Sequence#

  • nep - the nonlinear eigensolver context

  • maxnp - on input the number of requested points in the discretization (can be modified)

  • xi - computed values of the discretization

  • ctx - optional context, as set by NEPNLEIGSSetSingularitiesFunction()

Note#

The user-defined function can set a smaller value of maxnp if necessary. It is wrong to return a larger value.
