NEPGetIterationNumber

Gets the current iteration number. If the call to NEPSolve() is complete, then it returns the number of iterations carried out by the solution method.

Synopsis

#include "slepcnep.h" 
#include "slepcbv.h" 
PetscErrorCode NEPGetIterationNumber(NEP nep,PetscInt *its)
Not Collective

Input Parameter

nep  - the nonlinear eigensolver context

Output Parameter

its  - number of iterations

Note

During the i-th iteration this call returns i-1. If NEPSolve() is complete, then parameter "its" contains either the iteration number at which convergence was successfully reached, or failure was detected. Call NEPGetConvergedReason() to determine if the solver converged or failed and why.
