求助：matlab二次规划问题（quadprog函数）

lucky_boy-lx

运行quadprog函数后，出现如下警告：

Warning: Large-scale method does not currently solve this problem formulation,
switching to medium-scale method.

The system of equality constraints is consistent. Removing
the following dependent constraints before continuing:

Maximum number of iterations exceeded; increase options.MaxIter.
To continue solving the problem with the current solution as the
starting point, set x0 = x before calling quadprog.
但仍能得出结果，
问：结果有效吗？
补充：[x,Profit] = quadprog(H,f,A,b,Aeq,beq,lb,ub);
      其中，H：135*135
            A：14*135
            Aeq：30*135
      感觉不算大呀！
      而且几秒钟就运行完啦！
请帮忙分析一下，哪出了问题，谢谢！

函数用的不太正确，看提示
switching to medium-scale method.

谢谢楼上
-----------------------------------------------
exitflag =

     0


output =

       iterations: 200
       algorithm: 'medium-scale: active-set'
    firstorderopt: []
     cgiterations: []
          message: [1x181 char]


lambda =

      lower: [135x1 double]
      upper: [135x1 double]
      eqlin: [30x1 double]
    ineqlin: [14x1 double]

---------------------------------------
系统似乎已经自动转换到了   medium-scale method

问题貌似出在这儿了：
exitflag =

     0         ：Number of iterations exceeded options.MaxIter.
该怎么解决？
请赐教
谢谢
