首先需要做的工作是matlab编译器的设置，设置方法为：在Command window中输入mbuild-setup 显示如下
>>mbuild-setup
Please choose your compiler for building standalone MATLAB applications:
Would you like mbuild to locate installed compilers[y]/n?n%选择n
Select a compiler:
[1]Lcc-win32C2.4.1
[2]Microsoft Visual C++6.0
[3]Microsoft Visual C++.NET2003
[4]Microsoft Visual C++2005
[5]Microsoft Visual C++2005Express Edition
[6]Microsoft Visual C++2008
[0]None
Compiler:6%选择6，其他编译器可以选相应的选项，我没有验证过The default location for Microsoft Visual C++2008compilers is C:\Program Files\Microsoft Visual Studio9.0,
but that directory does not exist on this machine.
Use C:\Program Files\Microsoft Visual Studio9.0anyway[y]/n?n%选择n
Please enter the location of your compiler:[C:\Program Files\Microsoft Visual Studio9.0] D:\Program Files\Microsoft Visual Studio9.0%选择您自己的当前安装路径
Please verify your choices:
Compiler:Microsoft Visual C++2008
Location:D:\Program Files\Microsoft Visual Studio9.0
Are these correct[y]/n?y%看上述信息，如果正确选择y

Done... %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%至次编译器设置完成%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
在matlab的Command window中输入：
>>deploytool
Matlab产生deployment tool配置窗口
单击新建按钮，新建工程------>选择MATLAB Builder NE选项卡----->选择.NET Component 并添加工程名eaqual（测试用名，其实工程名称就是你导入C#后的命名空间名称,Matlab会在当前工作目录中新建文件夹文件夹名既为equal）---->点击ADD File按钮将你需要编译的MATLAB函数添加进当前工程，我这里导入的是D:\Program Files\MATLAB\R2008b\toolbox\aero\aero\angle2quat.m文件---->点击build.
deployment tool output窗口输出以下信息：
Build output(2009-03-2815:32:55).
[url=matlab:mcc%20-F%20%27E:%5CMATLAB%5Ceaqual.prj%27]mcc-F 'E:\MATLAB\eaqual.prj'[/url]
等待...................................有点久
当输出以下信息时编译成功了

Compilation completed succesfully.The output is located in E:\MATLAB\eaqual\distrib.
You can package the component by clicking on the"ackage"icon in the Deployment Tool
toolbar,or by clicking the Tools->ackage menu when the Deployment Tool panel is selected.To include additional files in the package,click Project->Settings).
生成的文件在工程文件夹里面
我的是E:\MATLAB\eaqual\distrib\angle2quat.dll
至此MATLAB的操作全部完成
打开VISUAL Studio2008新建C#工程我这里用的是控制台名为TestOfmatlab_consolt
我的是E:\Visual Studio2008\Projects\TEST\TestOfmatlab_consolt
添加引用E:\MATLAB\eaqual\distrib\angle2quat.dll
和D:\Program Files\MATLAB\R2008b\toolbox\dotnetbuilder\bin\win32\v2.0\MWArray.dll
(这里我没有用MATLAB画图，所以只引用MWArray.dll)
加入命名空间：
using https://www.doczj.com/doc/d819014049.html,.Arrays;
将下面代码加入Main函数
eaqual.Eaqual eq=new eaqual.Eaqual();
https://www.doczj.com/doc/d819014049.html,.Arrays.MWArray m=10,n=4,j=7,k;
MWArray S="XYZ";
k=eq.angle2quat((MWNumericArray)m,(MWNumericArray)n, (MWNumericArray)j,
(MWCharArray)S);
MWNumericArray temp=(MWNumericArray)k;
double[,]location=(double[,])temp.ToArray(MWArrayComponent.Real);
Console.WriteLine(location[0,0].ToString());
Console.WriteLine(location[0,1].ToString());
Console.WriteLine(k[2].ToString());
Console.WriteLine(k[3].ToString());
Console.WriteLine(k[4].ToString());
Console.ReadLine();
编译运行即可看到输出，此函数是姿态角转四元数函数，具体功能就不做说明了。这个例子输入输出参数的转换关系都有，大家自己看看就明白了
