c# 调matlab传字符串_终于学会C#调用matlab函数了，原来这么简单

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

FilesMATLABR2009btoolboxcompilerdeploywin32

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

FilesMATLABMATLAB Compiler Runtimev80binwin32;

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 FilesMicrosoft Visual Studio 8, but

that directory does not exist on this machine.

Use C:Program FilesMicrosoft Visual Studio

8.0 anyway [y]/n? n%选择n

Please enter the location of your compiler: [C:Program

FilesMicrosoft Visual Studio 9] D:Program FilesMicrosoft 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 FilesMicrosoft 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 FilesMicrosoft

Visual Studio 8". Trying to update options file: C:Documents and

SettingsAdministratorApplication

DataMathWorksMATLABR2009acompopts.bat From template:

D:PROGRA~1MATLABR2009abinwin32mbuildoptsmsvc80compp.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。

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:"magicprodistrib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 = "

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 += "

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

{

html_value += "

html_value += y[i, j];

html_value+="

}

html_value += "

}

html_value += "

Label1.Text = html_value;

}
