Newton Raphson method MATLAB Answers MATLAB Central October 11th, 2018 - I have a problem find the steady state solution of the following plant equation by using MATLAB codes Newton Raphson method many thanks This is Newton Raphson code Solving a Nonlinear Equation using Newton Raphson Methodbackward_euler, a MATLAB code which solves one or more ordinary differential equations (ODE) using the (implicit) backward Euler method, using fsolve() to solve the implicit equation.. Unless the right hand side of the ODE is linear in the dependent variable, each backward Euler step requires the solution of an implicit nonlinear equation.
