Sažetak
We present the local convergence analysis of two-step iterative methods free of
derivatives for solving equations and systems of equations under similar hypotheses based
on Lipschitz-type conditions. The methods are in particular useful for solving equations or
systems involving non-differentiable terms. A comparison is also provided using suitable
numerical examples
