SVDGetIterationNumber#

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

Synopsis#

#include "slepcsvd.h" 
PetscErrorCode SVDGetIterationNumber(SVD svd,PetscInt *its)

Not Collective

Input Parameter#

  • svd - the singular value solver context

Output Parameter#

  • its - number of iterations

Note#

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