E.g., Theme. Copy. dy1 = dy (x,y); % derivative at this time point. dy2 = dy (x+h,y+h*dy1); % derivative at next time point from the normal Euler prediction.The forward Euler method is an iterative method which starts at an initial point and walks the solution forward using the iteration y_ {n+1} = y_n + h f (t_n, y_n). Since the future is computed directly using values of t_n and y_n at the present, forward Euler is an explicit method.backward_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.From the series: Solving ODEs in MATLAB.
