LMEGetIterationNumber#

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

Synopsis#

#include "slepclme.h" 
PetscErrorCode LMEGetIterationNumber(LME lme,PetscInt *its)

Not Collective

Input Parameter#

  • lme - the linear matrix equation solver context

Output Parameter#

  • its - number of iterations

Note#

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