PEPGetIterationNumber#
Gets the current iteration number. If the call to PEPSolve() is complete, then it returns the number of iterations carried out by the solution method.
Synopsis#
#include "slepcpep.h"
PetscErrorCode PEPGetIterationNumber(PEP pep,PetscInt *its)
Not Collective
Input Parameter#
pep - the polynomial eigensolver context
Output Parameter#
its - number of iterations
Note#
During the i-th iteration this call returns i-1. If PEPSolve() is complete, then parameter “its” contains either the iteration number at which convergence was successfully reached, or failure was detected. Call PEPGetConvergedReason() to determine if the solver converged or failed and why.
