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 = "http://www.mamicode.com/

";
        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
