大家帮忙看看，我的程序哪里出错了
我自己编了个程序，不知道哪里出错了，一直是busy，不出结果，大家帮忙看看。拜托
程序如下：
function F = equation08729(x,y,z) %x代表α；y代表β；z代表q
syms x y z
n=23;f1=0;f2=0;g2=0;h1=0;h2=0;h3=0;

t=[126,118,40,67,164,638,750,69,71,7,22,124,91,139,70,436,19,357,49,26,163,108,110];
for i=2:n
for j=1:i-1
f1=f1+t(j);
end
f2=f2+(t(i)+z*f1)^y-(z*f1)^y;
g2=g2+log(t(i)+z*f1)-((t(i)+z*f1)/x)^y*log((t(i)+z*f1)/x)+(z*f1/x)^y*log(z*f1/x);
h1=h1+f1/(t(i)+z*f1);
h2=h2+f1^y;
h3=h3+(t(i)+z*f1)^(y-1)*f1;
end
f3=y/x^(y+1)*f2+(y*(t(1)/x)^y-n-y+1)/x;
g3=n/y+log(t(1)/x)-(t(1)/x)^y*log(t(1)/x)+g2;
h4=(y-1)*h1+y*z^(y-1)/x^y*h2-y/x^y*h3;

F=[f3;g3;h4];
%%%[x0,y0,z0] = [80; 1;0.5]; % Make a starting guess at the solution
%%%x0=80;y0=1;z0=0.5;
options=optimset('Display','iter'); % Option to display output
set(0,'RecursionLimit',10000);
[x,y,z] = fsolve(@equation08729,[80,1,0.5],options); % Call optimizer
