[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 8:0/Cj  
SJ]6_4=y*  
程序如下 :i&]J$^;  
^6 wWv&G[8  
clearclc |y^=(|eM  
h=1000;N=100; c^I^jg2v  
R=100;for i=2:101 o< @![P  
    theata(i)=asin(sqrt((i-1)/N));end  qNJc*@s  
theata(1)=0;for i=1:101 r;{$x  
%      r(i)=R*sqrt((i-1)/N);r(i)=sqrt(R^2/i) O}i+1  
end% r(1)=0; kt6)F&;$  
a=zeros(101,1);c=zeros(101,1); v@EErF  
x=zeros(101,1);y=zeros(101,1); FO*Gc Z  
a(1)=550;x(1)=-50; @)d_z

for i=2:100    k=2*a(i-1); M P8Sd1_=  
    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))]; @ujwN([I  
    x(i)=XY(1);    y(i)=XY(2); 1["i,8zB  
    FX=F-XY;    a(i)=(norm(FX)+norm(XY))/2; *H!BThft4  
    i    x(i) GST#b6S  
    y(i)end >B6*`3v  
plot(x，y）

请问楼主解决了吗
