Perturbed Functional Iterations: A Matrix Free Large-Scale Nonlinear System Solver in Applied Science with an Introduction to D-Mapping

Perturbed Functional Iterations is a large-scale nonlinear system solver. Nature is abundant with events simulated mathematically by nonlinear systems of equations and inequalities. These we call nonlinear models. This book will guide readers with the proper use of PFI, both in theoretical and practical settings.
