C# MATLAB混合编程

我附带把matlab配置过程也给大家上传上来。
【转载】终于学会C#调用matlab函数了，原来这么简单（也可以下载附件查看）
自己的配置：

（1）Microsoft Visual Studio 2005

（2）Matlab R2009a

（3）iis 6.0

第一步：

首先安装Matlab；

安装Visual Studio 2005或者更高版本；

安装MCRInstall.exe，我安装完Matlab之后在这里找得的：D:"Program Files\MATLAB\R2009b\toolbox\compiler\deploy\win32

点击：我的电脑-属性-高级-环境变量-系统变量-PATH-编辑，在变量值输入框中，不要删除以前的字符串，在最前面加入MCR的安装路径，如：D:"Program Files\MATLAB\MATLAB Compiler Runtime\v80\bin\win32; 然后确定、保存、重启电脑。（我就是不知道需要这两步，老是在C#创建Matlab的访问对象时，出现：“xxx的类型初始值设定项引发异常。”，完全不理解是什么原因，被耽搁了大量时间，直到安装了Matlab 2008b，仔细阅读它生成的readme.txt才知道）

第二步： 在matlab的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-win32 C 2.4.1

[2] Microsoft Visual C++ 6.0

[3] Microsoft Visual C++ .NET 2003

[4] Microsoft Visual C++ 2005

[5] Microsoft Visual C++ 2005 Express Edition

[6] Microsoft Visual C++ 2008

[0] None Compiler: 4 %选择4，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++ 2008 compilers is C:\Program Files\Microsoft Visual Studio 8, but that directory does not exist on this machine.

Use C:\Program Files\Microsoft Visual Studio 8.0 anyway [y]/n? n%选择n

Please enter the location of your compiler: [C:\Program Files\Microsoft Visual Studio 9] D:\Program Files\Microsoft Visual Studio 8.0 %选择您自己的当前安装路径

Please verify your choices: Compiler: Microsoft Visual C++ 2005 Location: D:\Program Files\Microsoft Visual Studio 8.0 Are these correct [y]/n? y %看上述信息，如果正确选择y

Warning: MBUILD requires that the Microsoft Visual C++ 8.0 directories "VC" and "Common7" be located within the same parent directory. MBUILD setup expected to find directories named "Common7" and "VC" in the directory: "C:\Program Files\Microsoft Visual Studio 8". Trying to update options file: C:\Documents and Settings\Administrator\Application Data\MathWorks\MATLAB\R2009a\compopts.bat From template: D:\PROGRA~1\MATLAB\R2009a\bin\win32\mbuildopts\msvc80compp.bat Done . . . 到此matlab编译器设置成功。

第三步： 编写m文件：

function y=mymagic(x)

y=magic(x);

第四步：建立项目：

在matlab中点击“File- new -Development Project” 自己选择项目保存目录和项目名，如E:"和magicpro.prj 类 型选择.NET Component，如果你要生成更通用的COM组件，选择Generic COM Component。添加刚才的m文件到这个新建的项目中去。点击Build the project按钮（这个按钮的图标和微软开发工具的Build图标一样）或者右击选择“build”，等待3，4分钟。建立成功。

The output is located in E:\magicpro\distrib. You can package the component by clicking on the "Package" icon in the Deployment Tool toolbar, or by clicking the Tools->Package menu when the Deployment Tool panel is selected. To include additional files in the package, click Project->Settings).

第五步： 打开2005.新建网站 新建C#网页添加引用：

选择.NET，选择MathWorks,.NET MWArrays API字样的一个组件添加引用：选择浏览，选择刚才用Deployment新建的项目的E:"magicpro\distrib目录的magicpro.dll文件 . 设置页面，一个文本框（输入魔方的维数）一个按钮（提交），一个标签（显示魔方）。 代码如下：

using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using MathWorks.MATLAB.NET.Arrays;
using magicpro;

public partial class Default2 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        Label1.Visible = false;
    }

protected void Button1_Click(object sender, EventArgs e)
    {
        Label1.Visible = true;
        string html_value = "<table >";
        int input = Convert.ToInt32(TextBox1.Text);
        magicpro.Magicpro m = new Magicpro();
        MWNumericArray x = new MWNumericArray(input);
        MWArray[] argsout = new MWArray[1];
        MWArray[] argsin = new MWArray[] { x };
        m.mymagic(1, ref argsout, argsin);
        MWNumericArray y = argsout[0] as MWNumericArray;
      
        TextBox1.Visible = false;
        Button1.Visible = false;
        for (int i = 1; i <= y.Dimensions[0]; i++)
        {
            html_value += "<tr>";
            for (int j = 1; j <= y.Dimensions[1]; j++)
            {
                html_value += "<td>";
                html_value += y[i, j];
                html_value+="</td>";
            }
            html_value += "</tr>";
        }
        html_value += "</table>";
        Label1.Text = html_value;
    }
}

运行输入4.点击按钮出现4阶魔方：

16 2 3 13

5 11 10 8

9 7 6 12

4 14 15 1 成功
