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 i-th iteration this call returns i-1. 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.
