how to visualize my code.

I made some code about FreeFall from Physics.

I compleded coding with numbers clearly.

The problem is that i do not know how to visualize this code properly.

I just can make linear line to visualize my code.

I want to make a moving box following my parabolic.

Also, i want to make small airplane following the horizontal line.

I tried to use SET command but i do not know how it works.

Thanks.

It's hard to understand exactly what you're looking for. It might help to upload a hand-drawn picture of what you want to create and upload some sample data for us to work with. This should solve the airplane bit.

Also a heads-up: some folks on this forum bristle at "send-it-to-me" requests because the forum is supposed to be for everyone to learn from. It's a subtle difference, but sending code directly by email feels less like community learning and more like free consulting.

I did not mean it. Actually I wanted to solve this problem and get the idea as soon as possible. And I do not check this community frequently. So I thought it would be great that you send me an email, i could check your answer on this web quickly. This was what i wanted to do.

By the way, I tried to draw a picture, but this is really bad.

function userinput

% Making a Target

clf

TargetCenter=floor(rand(1)*100); TargetHigh=TargetCenter+10;

plot([TargetCenter TargetHigh], [0 0],'m') axis([-10 110 0 100])

hold on

% UserInput

while 1 % velocity v=input('Velocity(m/s): ');

    %Height
    H=50;

    % g
    g=9.81;

    % time
    t=sqrt(2*H/g);

    % time interval
    dt=0.3;

    % 
    R0=v*t;

    for x=0:dt:R0

   %want to be a moving box!
   y=-9.8/(2*v.^2)*x.^2+50;
   plot(x,y);

    % want to be in the shape of an airplane 
    y=50;
    plot(x,y);

    drawnow;
      end

    if R0>=TargetCenter & R0<=TargetHigh
        fprintf('Success!\n\n');
        break;
    end

end

this is my code. I tried to fix 4 points around the CenterPoints of each two linear lines. Then I tried to move the box and airplane by using SET command. But it was not working.

I tried as many things as possible, but failed. hope you can give me an idea.
