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.
