I need to make this stick figure move left and right, and up and down. It should be an animation that shows the stick figure sliding along the x axis, likely using linspace for a time vector.
Here is the code for the stick figure:
joints = [-0.5 .9; -0.4 1.2; -0.2 1.4; 0.0 1.4; 0.2 1.4; ...
0.4 1.2; 0.3 .85; 0.0 1.6; -0.5 0.0; -0.4 0.0; ...
-0.3 0.5; 0.0 0.9; 0.3 0.5; 0.5 0.0; 0.7 0.0];
bones1 = [ 1 2; 2 3; 3 4; 4 5; 5 6; 6 7; 4 8; ...
4 12; 9 10; 10 11; 11 12; 12 13; 13 14; 14 15];
for k=1:size(bones1,1)
plot([joints(bones1(k,1),1), joints(bones1(k,2),1)], [joints(bones1(k,1),2), joints(bones1(k,2),2)])
hold on
end
plot(joints(:,1), joints(:,2), 'o')

Have a look at this function to create animated lines in MATLAB:
