麻烦帮忙看看怎么解决，出现了以下问题：

Question

主函数：
x0=[0.1 0.05 3.5];
lb=[0 0 3];
ub=[0.8 0.6 10];
a=[-1 1 0;-1 0 0;0 -1 0;0 0 -1];
b=[0 0 0 -3]';
options=optimset('tolcon',1e-8);
[x,fval]=fmincon(@cdz_f,x0,a,b,[],[],lb,ub,@cdz_v,options)

辅助函数（非线性约束）
function[c,ceq]=cdz_y(x);
c(1)=154.34*x(1)/(x(1)^4-x(2)^4)-((x(1)-x(2))/x(1))^(3/2);
ceq=[];

主函数：[x,fval]=fmincon(@cdz_f,x0,a,b,[],[],lb,ub,@cdz_y,options)辅助函数（非线性约束）function[c,ceq]=cdz_y(x);c = 154.34*x(1)/(x(1)^4-x(2)^4)-((x(1)-x(2))/x(1))^(3/2);ceq=[];
