[求助] 优化模型出现错误，各位大神帮忙指导下，谢谢已有1人参与

function f=bibi_mubiao(x)
f=pi*(x(2)^2+0.875*x(1)^2)*x(3)+x(3)*x(4)*(x(1)-x(2))^2*(0.5-(x(1)-x(2))/(96*x(5))-(x(1)-x(2))^3/(10240*x(5)^3));

function [g,ceq]=bibi_yueshu(x)
g(1)=3082131360*(x(2)+x(5))-3200*x(2)^2*x(3)*x(4)*x(5)*tan(4*pi/180);
g(2)=210000-506.25*x(2)^3;
g(3)=x(1)-x(2)-4*cos(4*pi/180)*tan(5*pi/(6*x(4)))*(x(2)-x(5)-sqrt(x(5)^2-((x(2)-x(5))/(4*cos(4*pi/180)))^2));
ceq=[];

x0=[35.135,27.3825,6.6500,24,4.5000];
A=[-1,1,0,0,1;1,-1,0,0,-2];
b=[0;0];
[x,fval,exitflag,outflag]=fmincon(@bibi_mubiao,x0,A,b,[],[],[],[],@bibi_yueshu)

我编辑了三个M文件，但是在命令窗口输出bibi运行时Warning: The default trust-region-reflective algorithm does not solve problems
with the constraints you have specified. FMINCON will use the active-set
algorithm instead. For information on applicable algorithms, see Choosing the
Algorithm in the documentation.

Warning: Your current settings will run a different algorithm (interior-point)
in a future release.

matlab完全没什么基础，照着一个例子编的。这是出现什么问题？各位大神帮忙看看程序编辑哪里有问题？万分感谢
