Although this is the most basic non-linear solver, it is surprisingly powerful. It is based on the Newton-Raphson method in chapter 9.6-7 of Numerical Recipes in C. In general for well behaved functions and decent initial guesses, its convergence is at least quadratic. However it may fail ...

A Non-Linear system of equations is given by, (x1 ^ 3) + (x2) = 1 (x1) + (x2) = 0 Write a MATLAB function that uses the Newton-Raphson method to solve a nonlinear system of equations. The function should accept a function handle for a the nonlinear system, a function ...
The power flow problem is generally solved by the Newton-Raphson method with a sparse direct solver for the linear system of equations in each iteration. While this works fine for small power flow problems, we will show that for very large problems the direct solver is very slow and we pres...
The next stage is to create the Newton-Raphson solver itself. The function template will accept an object of type T (the functor) and two pointers to member functions (methods) of T, g and g_prime. Here is the listing for newton_raphson.h: #ifndef __NEWTON_RAPHSON_H #define __NEWT...
