# 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.
