[MATLAB工具箱] 循环调用fmincon工具箱问题

[lijun19841022]

请大侠给看看我的程序出的问题：

%目标函数m文件：
function f=fun3(x,r)
f=8/(4.4^2)*x(2)*(x(1)-1)*2/3.14*acos(exp((-1.5)*(22-r)/22/sin(atan((1-x(1))/(0.2*r)/(1+x(2))))))*((0.2*r)^3);

**************************

%约束方程m文件：
function [c,ceq]=mycon(x,r)
c=[];
ceq=x(1)*(1-x(1))*2/3.14*acos(exp((-1.5)*(22-r)/22/sin(atan((1-x(1))/(0.2*r)/(1+x(2))))))-x(2)*(1+x(2))*((0.2*r)^2);

*****************************
命令窗口输入：
for r=0:2:22;
b0=10/4.4*exp(12*r/22);
options = optimset('LargeScale','off'); % run medium-scale algorithm
x = fmincon(@(x)fun3(x,r),[0.1776;b0],[],[],[],[],[],[],
@(x)mycon(x,r),options)
a=x(1);
b=x(2);
disp(['a=',num2str(a),',b=',num2str(b)]);
end
********************
运行结果：

than options.TolFun and maximum constraint violation is less
than options.TolCon.

问题：r从0—22，步长为2，应该出12个结果，但运行后只出来6个，左下角显示continue entering statement，好像是陷入了死循环，估计是程序有漏洞，请大侠给看看，感激不尽啊！我的email：[email protected]
