Root Finding Cauchy Integration Method

A root finding algorithm for complex functions based on Delves & Lyness method using Cauchy Integration Method.

A root finding algorithm for complex functions based on Delves & Lyness method using Cauchy Integration Method. The search is performed in a specified search box defined by the user. The function of interest can be implemented separately with any number of arguments and accepts complex expressions. The function of interest must be analytic within the search box. Results are polished with Newton-Raphson iteration for maximum accuracy. Automatic Differentiation is required.
