[求助]关于配焦椭流线法的matlab编程实现问题 [复制链接]

求前辈指点迷津，感觉椭流线表达式有问题，又不知道哪里不对 . L]!*

程序如下 QjFE  
;<s0~B#9}  
clearclc F t;[>o  
h=1000;N=100; *|.-y->  
R=100;for i=2:101 T3/Gl6f  
    theata(i)=asin(sqrt((i-1)/N));end WTj,9  
theata(1)=0;for i=1:101 j7=x&)qbx  
%      r(i)=R*sqrt((i-1)/N);r(i)=sqrt(R^2/i) PLQLGb4f_;  
end% r(1)=0; tQ(gB_
 
a=zeros(101,1);c=zeros(101,1); Kfs|KIQ>=  
x=zeros(101,1);y=zeros(101,1); F'JceU  
a(1)=550;x(1)=-50; V?-OI>  
y(1)=0; K7]+. f  
3/RNStd<L!  
for i=2:100    k=2*a(i-1); 1|H(q  
    F=[h,r(i-1)/2-r(i)/2];    XY=((k^2-norm(F)^2)/(2*k-2*norm(F)*cos(pi-theata(i))))*[cos(pi-theata(i)),sin(theata(i))]; Xs$UpQo   
    x(i)=XY(1);    y(i)=XY(2); S!.H _=z%p  
    FX=F-XY;    a(i)=(norm(FX)+norm(XY))/2; uzaDK  
    i    x(i) K`twbTU  
    y(i)end mI3 \n  
plot(x，y）

请问楼主解决了吗
