Numerical method for solving a nonlinear inverse diffusion equation

Numerical Method is a way in solving a model of a problem mathematically and predicts the behaviour of the problem. That is why this method is very important for both natural and manmade process. Some basic theory of the Numerical Method has been applied in our daily life such as chemistry, physics,...
