I want to make 3D trajectory of x and y, i have tried it in 2D but nothing is displayed using the plot here is my code.

    X=1;
    Y=0;
    Z=1;
    X=-10*X+10*Y;
    Y=28*X-Y-X*Y;
    Z=-(8/3)*Z+X*Y;
    v0 = 2; % velocity 
    T = 5000; % time
    t = 0:0.01:T;
    x = v0* cos(Z);
    y = v0* sin(Z);
    figure,plot(x,t,y,t);

After the first (x,y,z)=(1,0,1) assignment, the lines before velocity states (X,Y,Z)=(-10,-280; 280-8/3)=(-10,-280,832/3), and so, in the last part of your code, (x,y) are constant values, independent of the t values.

I don't know what is the trajectory you're trying to plot
