    Challenging trick

    Hi Guys Here is a challenging trick for you: Suppos that you have this star.m file containg an ODE with the needed parameters: function dC = star(t,C) dC = zeros(1,1); Gn=1; N=2; f=3; w=4; dC = (1/2)*Gn*N*C(1)+f*cos(w*t-C(1)) Now to solve this equation you simply create the following file: t...

    crazy loop

    Hi Guys Have a look at the following simple matlab code: x=[1;2;3;4;5;6;7;8;9;10]; y=[5;4;3;6;7;8;5;4;3;2]; z=[1;2;-7;-4;5;-1;4;-9;-6;5] x1 = zeros(m, 1);% initialise output matrix y1 = zeros(m, 1); z1 = zeros(m, 1); for i = 1:m; x1(i) = x(i); y1(i) = y(i); z1(i) =...
