Question

急急急！！各位大虾帮帮忙啊 ！！！明天就交的！！！谢谢啦！！

matelab 绘制凸轮廓线
程序： global X1 Y1 X Y varphi
XA=0; YA=0; X=0; Y=0; r2=10; L0=100
varphi=linspace(0,2*pi,180)
for i=1:180
delta=varphi(i)
s(i)=10*cos(delta)
beta(i)=pi/4*cos(delta)
Ds=-10*sin(delta)
Dbeta =-pi/4*sin(delta)
q= ((L0+s(i))*sin(delta-beta(i))*(1-Dbeta)-Ds*cos(delta-beta(i)))
m= ((L0+s(i))*cos(delta-beta(i))*(1-Dbeta)+Ds*sin(delta-beta(i)))
if m>0
u(i)=delta-beta(i)-pi-atan(q/m)
else
u(i)=detal-beta(i)-atan(q/m)
end
X1 (i)= r2*cos(delta-beta(i)-u(i))+(L0+s(i))*cos(delta-beta(i))
Y1(i)=-r2 *sin(delta-beta(i)-u(i))-(L0+s(i))*sin(delta-beta(i))
X (i)= X1(i)*cos(delta)- Y1(i)*sin(delta)
Y(i)=X1 (i)*sin(delta)+ Y1(i)*cos(delta)
theta(i)=-varphi(i)+atan(X1/Y1)
rho(i)=sqrt(X (i)^2+Y (i)^2)
figure(4)
polar(theta,rho);
end
但运行出来图轮廓线只有部分不全啊 怎么补全 ？？我的哪里出错了？？谢谢！！！万分感激！！！
