The second order Runge--Kutta method (denoted RK2) simulates the accuracy of the Tylor series method of order 2. Although this method is not as good as the RK4 method, its derivation illustrates all steps and the principles involved. We consider the initial value problem y ′ = f ( x, y), y ( x 0) = y 0 that is assumed to have a unique solution.

Oct 29, 2017 · I have written the code for the RK2 Method in Matlab as: function [w, t, h] = rk2 (dom, f, w0, h) % A naive implementation of RK2 method. % Inputs: % dom: time domain % f: an anonymous function defined by the RHS of original ODE IVP % y0: initial value % h: step size T = diff (dom); N = ceil (T/h); h = T/N; t = dom (1):h:dom (2); w = zeros (N+1, 1); w (1) = w0; for i = 1:N k1 = h*f (t (i), w (i)); k2 = h*f (t (i)+h/2, w (i)+k1/2); w (i+1) = w (i) + k2; % midpoint method end end.

Note that I have not checked you have implemented the RK2 algorithm correctly. I have just modified the code that you have provided. You don't need to change very much at all. You should preallocate (which is good practice) y = zeros(2,nstep+1);, where column n of y is the solution at time n-1. You need to set the initial condition:

Commented: Mohamed Ellabban about 2 hours ago. Task: You have to use this method to solve the following IVP: An RL circuit has an emf of 5 V, a resistance of 50 Ω, an inductance of 1 H, and no initial. current ( i.e i (1)=0). Find the current in the circuit at any time t. The formula is: Ri+L (di/dt)=V. Sign in to answer this question.

and the basic RK2 iteration: y(:,n+1) = y(:,n)+k2; How many such changes did you make in rk2_many.m? You must alter all calls to rhs.m to rhs2.m in the script rk2_many.m. Add a line of code to plot i.e. y(1,:) as a function of , i.e. t (see plotting). The MATLAB function rhs2.m is very similar to rhs.m from last week.
