<P>小弟初学,请教各位一个问题.<br>我的 .M文件如下:<br><br>function [z]=myfun2(x)<br>L = [38.8263, 35.4687, 25.9806]<br>M = [0.0014, 15.7895, 28.8524]<br>N= [ -2.0010, -2.9670, -3.9326]<br>z= 0;<br>for k= 1:30<br>r(k)=(sqrt((L(k)-x(3)*N(k)-x(1)).^2+(M(k)-x(4)*N(k)-x(2)).^2)-x(5)).^2<br>z= z+r(k)<br>end<br>在matlab 中执行的命令是 :<br>x0=[0,0,1,1,38.00];<br>[x, fval, exitflag, output]= fminunc(@myfun2, x0)<br>这是个优化问题,我本来打算在vb中直接编程实现,可是做得不好,现在打算用matlab与vb 的接口完成这个问题,如果用comtool 的话 ,到VB 里怎样继续做呢?<br>请各位指点一下!</P>

vb调用matlab的com组件前面很多了，自己找一下<BR>如果有问题在问

<P>End Sub<br>这个是用引用MATRIXVB 编的程序,为什么vb 提示我说fminu找不到呢,而且在matlab里命令行输入的<br>x0=[0,0,1,1,38.00];到vb里怎么处理啊?</P>
