【转】Matlab和C#混合编程

本文转载自：http://emuch.net/html/201311/6617105.html

在实验室算法演示和工程应用中存在这样的困惑：

1. Matlab精通各种数值计算和算法，但是没有优美的界面，更不用说对数据库访问操作。

2.Visual studio（C#）拥有完美的界面编程，窗口或网络编程已经优越的数据库访问等优势。

-------------------------------------------------------------

3. 国外有一本书叫：MATLAB C# Book图书(已经放到压缩包中了)，看过以后收获不少。

4. 结合各种材料，我使用visual studio 2012+ matlab 2013a实现了从

Winfrom调用Matlab命令行绘图

Winfrom调用 .m文件编译的dll并在webBrowser中显示结果





调用Matlab命令demo





调用Dll demo





解决方案结构





压缩包中包含MATLABCSharp.pdf



下载 WinFormCallMatlab.rar


下载 vs2012matlab混合编程.rar

谢谢各位捧场。

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 /n? n %选择n

Select a compiler:

Lcc-win32 C 2.4.1

Microsoft Visual C++ 6.0

Microsoft Visual C++ .NET 2003

Microsoft Visual C++ 2005

Microsoft Visual C++ 2005 Express Edition

Microsoft Visual C++ 2008

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 /n? n%选择n

Please enter the location of your compiler: 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 /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。

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;

MWArray argsin = new MWArray { x };

m.mymagic(1, ref argsout, argsin);

MWNumericArray y = argsout as MWNumericArray;



TextBox1.Visible = false;

Button1.Visible = false;

for (int i = 1; i <= y.Dimensions; i++)

{

html_value += "<tr>";

for (int j = 1; j <= y.Dimensions; j++)

{

html_value += "<td>";

html_value += y;

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
