在 MATLAB Online 中打开

Use a for loop, line(), and pause(). If the lines are connected, you can use line() once. If the line segments are not touching, then it's probably easiest to call line twice with "hold on" in between (or else separate the two segments with nan's).

Sounds like homework so I'll just give a hint.

for angle = 0 : 360
  x1 = ....
  x2 = ....
  x3 = .....
  x4 = ....
  x1 = ....
  x2 = ....
  x3 = .....
  x4 = ....
  line([x1,x2,x3,x4], [y1,y2,y3,y4]);
  drawnow;
  pause(.5); % Pause so we can see it.
end
