PLEASE HELP: MY MATLAB CODE STILL ISNT WORKING

THIS IS MY CODE:

x = [-1 , 1, 1, 1,-1 ];

y = [-1/3,-1/3, 0, 1/3, 1/3];

g = hgtransform;

patch('XData',x,'YData',y,'FaceColor','black','Parent',g)

axis equal

xlim([-11 11])

ylim([-11 11])

xs = linspace(-10,10,100);

ys = 10*cos(xs);

ampx = 8;

ampy = 6;

w = 1;

phi = 0;

damp = .05;

e = exp(1);

e(t) = (e^(-damp*t));

for t=linspace(0,28*pi/2,5600)

   g.Matrix = makehgtform('translate',-ampx*e(t)*cos(w*t+phi),-ampy*et*((sin(w*t+phi))^2),0);

   drawnow

   pause(.0001) % putting this statement will make you feel that .. swinging like a cradle in movie, it will slow down the plotting

   line([0 0], [-11 11]); % this will give vertical lone between points which can acts as cords

   line([-11 11], [-11 11]); % right side vertical line

end

I NEED TO ADD 3 things:

1. a vertical line at each end of the swing, to act as the cords

2. I need to get the swing to slow down and come to a stop over time like a normal swing would,

but the swing should continue to stay on the same arc (also like a normal swing does)

please help

3. MY SWING DOESNT MOVE ANYMORE. NOT SURE WHAT HAPPENED

please...all help appreciated!

Explanation / Answer

For the above program:

1. Adding a vertical line at each of the swing

   simple command is line([x x], [y1 y2])

x= -1: .0001:1; %// Time values, were the swing stop at this time inreval //

ystart = [ -1/3 -1/3];

yend=[1/3 1/3];

figure; hold on;

for idx= 1 : nume1(ystart)

plot([ (idx) (idx)], ystart(idx) yend(idx)]);
