我附帶把matlab配置過程也給大家上傳上來。
【轉載】終於學會C#調用matlab函數了，原來這麼簡單（也可以下載附件查看）
自己的配置：

（1）Microsoft Visual Studio 2005

（2）Matlab R2009a

（3）iis 6.0

第一步：

首先安裝Matlab；

安裝Visual Studio 2005或者更高版本；

安裝MCRInstall.exe，我安裝完Matlab之後在這裡找得的：D:"Program Files\MATLAB\R2009b\toolbox\compiler\deploy\win32

點擊：我的電腦-屬性-進階-環境變數-系統變數-PATH-編輯，在變數值輸入框中，不要刪除以前的字串，在最前面加入MCR的安裝路徑，如：D:"Program Files\MATLAB\MATLAB Compiler Runtime\v80\bin\win32; 然後確定、儲存、重啟電腦。（我就是不知道需要這兩步，老是在C#建立Matlab的訪問對象時，出現：“xxx的類型初始值設定項引發異常。”，完全不理解是什麼原因，被耽擱了大量時間，直到安裝了Matlab 2008b，仔細閱讀它產生的readme.txt才知道）

第二步： 在matlab的Command window中輸入mbuild -setup顯示如下

>> mbuild -setup

Please choose your compiler for building standalone MATLAB applications: Would you like mbuild to locate installed compilers [y]/n? n %選擇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 %選擇4，其他編譯器可以選相應的選項，我沒有驗證過

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%選擇n

Please enter the location of your compiler: [C:\Program Files\Microsoft Visual Studio 9] D:\Program Files\Microsoft Visual Studio 8.0 %選擇您自己的當前安裝路徑

Please verify your choices: Compiler: Microsoft Visual C++ 2005 Location: D:\Program Files\Microsoft Visual Studio 8.0 Are these correct [y]/n? y %看上述資訊，如果正確選擇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編譯器設定成功。

第三步： 編寫m檔案：

function y=mymagic(x)

y=magic(x);

第四步：建立項目：

在matlab中點擊“File- new -Development Project” 自己選擇項目儲存目錄和項目名，如E:"和magicpro.prj 類 型選擇.NET Component，如果你要產生更通用的COM組件，選擇Generic COM Component。添加剛才的m檔案到這個建立的項目中去。點擊Build the project按鈕（這個按鈕的表徵圖和微軟開發工具的Build表徵圖一樣）或者右擊選擇“build”，等待3，4分鐘。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： 開啟2005.建立網站 建立C#網頁添加引用：

選擇.NET，選擇MathWorks,.NET MWArrays API字樣的一個組件添加引用：選擇瀏覽，選擇剛才用Deployment建立的項目的E:"magicpro\distrib目錄的magicpro.dll檔案 . 設定頁面，一個文字框（輸入魔方的維數）一個按鈕（提交），一個標籤（顯示魔方）。 代碼如下：

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;
    }
}


運行輸入4.點擊按鈕出現4階魔方：

16 2 3 13

5 11 10 8

9 7 6 12

4 14 15 1 成功
