EPSGetIterationNumber
Gets the current iteration number. If the call to EPSSolve() is complete, then it returns the number of iterations carried out by the solution method.
Synopsis
#include "slepceps.h"
PetscErrorCode EPSGetIterationNumber(EPS eps,PetscInt *its)
Not Collective
Input Parameter
 eps   the eigensolver context

Output Parameter
 its   number of iterations

Note
During the ith iteration this call returns i1. If EPSSolve() is
complete, then parameter "its" contains either the iteration number at
which convergence was successfully reached, or failure was detected.
Call EPSGetConvergedReason() to determine if the solver converged or
failed and why.
