求助:fmincon工具箱问题
<P><FONT size=5><STRONG>各位大侠:<BR>我用fmincon工具箱时,总是只优化初值一次,不知哪里有问题,运行程序如下:</STRONG></FONT><BR>y0=[-30000;-40000];<BR>lb=[-120000;-150000];<BR>ub=[-30000;-30000];<BR>options=optimset('GradObj','off');<BR>=fmincon('ff1',y0,[],[],[],[],lb,ub,'mycon',options)<BR><FONT size=4><STRONG>计算后的结果显示如下:<BR></STRONG></FONT>In D:\MATLAB6p5\toolbox\optim\fmincon.m at line 213<BR>Optimization terminated successfully:<BR> Magnitude of directional derivative in search direction <BR>less than 2*options.TolFun and maximum constraint violation <BR>is less than options.TolCon<BR> No Active Constraints</P><P>y =</P>
