This program draws a Crucis given a point and

the arm length.function [x,y] = Crucis(x,y,L)

  [x1,y1] = forward(x,y,L);

  [x2,y2] = downward(x1(end),y1(end),L);

  [x3,y3] = backward(x2(end),y2(end),L);

  [x4,y4] = upward(x3(end),y3(end),L);

  x = [x1,x2,x3,x4];

  y = [y1,y2,y3,y4];

  plot(x,y)

  axis equal

end
