Abstract
We provide a local convergence analysis for the Secant method in a Banach space setting under Hölder continuous conditions. Using more precise estimates, and under the same computational cost, we enlarge the radius of convergence obtained in Ren and Wu (J Comput Appl Math 194:284–293, 2006).
