[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 s$6#3%h  
h_!"CF<n  
程序如下 tYa8I/HpT  
tn1aH +  
clearclc 3Gv i!h7  
h=1000;N=100; WE]^w3n9  
R=100;for i=2:101 ~T9[\nU\  
    theata(i)=asin(sqrt((i-1)/N));end  Z.JTq~`I  
theata(1)=0;for i=1:101 [_@OCiV5)  
%      r(i)=R*sqrt((i-1)/N);r(i)=sqrt(R^2/i) {jG`l$$  
end% r(1)=0; YfKty0  
a=zeros(101,1);c=zeros(101,1); gs>cx]>  
x=zeros(101,1);y=zeros(101,1); ic#drpl,  
a(1)=550;x(1)=-50; q(W@=-uDK  
y(1)=0; -Ma"V

for i=2:100    k=2*a(i-1); q4=RE  
    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))]; xd@DN;e  
    x(i)=XY(1);    y(i)=XY(2); k#n=mm'N9  
    FX=F-XY;    a(i)=(norm(FX)+norm(XY))/2; rkl7p?

请问楼主解决了吗
