[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 {BN#h[#B{  
m]6mGp  
程序如下 TQF| a\M'  
O m|_{  
clearclc e'NJnPO  
h=1000;N=100; 0*3R=7_},o  
R=100;for i=2:101 _`j7clEz  
    theata(i)=asin(sqrt((i-1)/N));end {UI+$/v#  
theata(1)=0;for i=1:101 *w`sM%]Rq  
%      r(i)=R*sqrt((i-1)/N);r(i)=sqrt(R^2/i) sUO`uqZV  
end% r(1)=0; |tH4:%Q'  
a=zeros(101,1);c=zeros(101,1);  ?(1y

请问楼主解决了吗
