How to apply runge kutta method for system of equations that are coupled ODE's? like x1'= -3*x2 and x2'=(1/3)*x1? I tried the code below but get an error on function define saying too may input arguments.
y=zeros(1,length(x)); z=zeros(1,length(x)); y(1)=0; z(1)=0; Fx1= @(x2)(3)*x2; Gx2=@(x1)(1/3)*x1; for i=2:(length(...
