gaot工具箱使用求极大值

A. matlab6.5+gaot工具箱和matlab7.0自带工具箱的效果一样吗

matlab7.0自带的工具箱版本未必都是7.0，我的这台电脑装的也是.5，看看它的版本吧。

B. 怎样才能知道已经成功安装了遗传算法的工具箱呢

我的工具箱是在咱们的论坛里面下的.......

C. MATLAB中ga函数（神经算法）调用提示输入变量太多，求大神指点下ga函数的用法

matlab自带工具箱和gaot中ga函数名字冲突，想用哪一个将其路径置顶提前即可。

D. MATLAB自带的GA工具箱，有谁知道麻烦告诉一下！求教！！！

请问matlab6.5 gaot工具箱和matlab7.0自带工具箱使用起来有区别吗？多谢了matlab7.0自带的工具箱版本未必都是7.0，我的这台电脑装的也是6.5，看看

E. 怎样用MATLAB求极大值

syms x
y=x*sin(x) ;
dy=diff(y);% 一阶导数
d2y=diff(dy);%二阶导数
x1=double(solve(dy));% 找出导数为0的点，就是极点
x2=subs(d2y,x1)

% 如果一阶导数为零，二阶导数小于零，则为极大点

F. linear equalities怎么写 matlab工具箱

的工具箱，分别是：GAOT，美 国北卡罗来纳大学开发；GATBX，英国谢菲尔德大学开发；GADS，Matlab7 以后 的版本中自带的。GATBX 可以包含GAOT，而GADS 显然年代又近了一些。这里 主要讲的是GADS 。 GADS （Genetic Algorithm and Direct Search Toolbox ）遗传算法与直接搜索工 具箱。可以在命令行中直接使用，在 M 文件的程序中调用 ga 函数，或在 GUI 界面中使用它来解决实际问题。在不同的Matlab 版本中启动方法稍有区别。以 笔者的Matlab 2010b 为例，启动有两种方法： 1、 在Matlab 命令行中输

G. matlab遗传算法工具箱的问题

还是自己编写吧工具箱好多实际问题不能解决

H. matlab2012中如何添加遗传算法工具箱-GAOT

可以找下龚纯，王正林的《精通MATLAB最优化计算（第2版）》这本书

I. 请教怎么在matlab上安装遗传算法工具箱啊，为什么我安不上啊

安装步骤

1.将GAOT工具箱文件拷贝至Matlab文件夹下，具体路径为：
C:\program files\MATLAB\R2009a\toolbox。（也可以放在其他路径，不一定放在toolbox里面，比如C:\program files\MATLAB\R2009a也行）。

2.将GAOT工具箱路径加入Matlab文件路径之中。流程为：File-->Set Path-->Add with Subfolders。即，将C:\program files\MATLAB\R2009a\toolbox\gaot文件夹加入该路径系统中。

3. 重新启动Matlab，运行。

4. 但是在重新启动后，你会发现在命令窗口，会出现如下警告。即安装遗传工具箱后出现问题：Warning: Name is nonexistent or not a directory: \afs\eos\info\ie\ie589k_info\GAOT
解决方案：打开gaot文件夹下的startup.m，这里面写着“path(path,'\afs\eos\info\ie\ie589k_info\GAOT');”只要将“\afs\eos\info\ie\ie589k_info\GAOT”改为goat当前所在的目录，即“C:\program files\MATLAB\R2009a\toolbox\gaot”就可以了

5.测试是否安装成功，方法如下：在命令窗口输入：edit ga出现如下函数：function [x,fval,exitFlag,output,population,scores] = ga(fun,nvars,Aineq,bineq,Aeq,beq,lb,ub,nonlcon,options)此时你会发现这是MATLAB自带的ga函数，并不是你想要的工具箱中的ga函数，这样会在以后应用工具箱编写程序是发生错误。

6. 解决上述问题的方法：为了统一，不管你是高版本还是低版本，都可以通过将GAOT工具箱中的ga重命名为gaot_ga(名字可以随你定，但是不能改为大写GA，原因是MATLAB会默认大小写函数是同一个函数，不信你可以用edit ga和edit GA验证)，来实现解决上述问题。
这样整个的GAOT工具箱安装完备。
