`boolean` | `converged(Vector r)` Checks for convergence
`boolean` | `converged(Vector r, Vector x)` Checks for convergence
`IterationReporter` | `getIterationReporter()` Returns current iteration reporter
`Vector.Norm` | `getNormType()` Returns the vector-norm in use
`boolean` | `isFirst()` Returns true for the first iteration
`int` | `iterations()` Number of iterations performed
`void` | `next()` Increases iteration counter
`double` | `residual()` Returns current residual
`void` | `setFirst()` Resets the iteration
`void` | `setIterationReporter(IterationReporter monitor)` Sets new iteration reporter
`void` | `setNormType(Vector.Norm normType)` Sets the vector-norm to calculate with
