原文:【原创】Matlab.NET混合编程技巧之——直接调用Matlab内置函数(附源码)
在我的上一篇文章【原创】Matlab.NET混编技巧之——找出Matlab内置函数中，已经大概的介绍了matlab内置函数在混合编程中的优点，并通过程序找出了matlab中的大部分内置函数，当然更多人关心是如何像我所说得那样，不用直接编译，就直接在C#中调用这些内置函数。本文就带你揭开这些谜团。
声明，这篇文章是需要一点点混合编程基础的，基本概念和过程要懂一点，如果能简单成功混编一个简单的计算或者绘图例子，可以更容易理解。
传统的Matlab.NET混合编程有2种方式：
1)Matlab编写好M函数，利用deploytool编译m函数生成dll，在C#项目中引用并调用；
2)基于接口的编写方式，也是利用deploytool工具，过程繁琐一点，对编程人员素质要求高一点，但不需要进行繁琐的数据类型转换。我的博客有一篇文章专门介绍了这个混合编程方式，也有例子，大家有兴趣的可以看看：http://www.cnblogs.com/asxinyu/archive/2013/05/16/3082299.html
不管上面用哪种方式，Matlab和C#混编的基本步骤，大概都是下面的过程：
1) 编写M函数，并首先在Matlab中测试是正确可以调用的。注意命名规范，注释规范；
2) 使用命令打开 deploytool工具，设置项目名称，选择类型：.NET Assembly，然后新建一个类，并添加编写好的M函数
3) 编译，生成dll,并在C#项目中添加引用（还需要引用对应版本的MWArray），利用对象浏览器查看生成dll的方法结构，并根据Matlab和C#的类型转换规则，进行数据转换即可， 如果是接口的编程，这个过程相对要简单。
为了好我们今天的目的相匹配，特意封装一个简单的内置函数，plot，来画一个简单的图形，如下所示M函数
1 function PlotTest(n) 2 %编写一个简单的函数，对plot进行简单封装一下 3 plot(1:n,1:n); 4 %测试正确，才可以进行下一步工作
注意，混编必须是m函数function的形式才能被调用。上述函数简单测试一下，没有问题（复杂的函数一定要多测试，否则后续调试非常困难）。继续下一步。
在Matlab工作区输入命令：deploytool,然后得到下面界面，输入混编项目的名称，选择存储位置，关键的是类型那里一定要选择".NET Assembly"。如下图所示：
选择“OK”之后，下一步matlab界面右侧会出现项目解决方案，需要添加类名称和M文件。这个类名称，就是编译完成之后C#项目中的类对象名称，然后添加我们刚才上一步编写的“PlotTest.m”,然后编译即可，如下图所示：
到此为止，一个常规 简单的Matlab.NET混编已经完成了60%了。编译完成之后，打开“Package”选项卡，即可看到生成的dll文件，然后点击右键，打开文件夹即可，如下图所示：
这个过程很关键，其实包含很多信息，只不过95%以上的人都没有注意到其实混编生成的dll是有源文件的，通过查看源文件就应该知道混编的原理，只不过这是matlab自动生成 而已。那看看生成的源码吧。
打开Matlab混编项目的目录，可以看到有2个文件夹，"distrib”，“src”2个文件夹。"distrib"文件夹就是上面图中生成的dll，注意有2个dll,1个是“项目名称.dll”,一个是“项目名称Native.dll”，这2个dll的差别可以通过"distrib"文件夹源码来观察。“distrib”就是源代码的文件夹。如下图所示，src文件夹的文件示意图：
我们2.2中新建的类名是TestDemo,所以生成的的源码名称也是TestDemo,看看这2个cs文件中的代码，同时类的方法也可以在VS中通过对象浏览器来查看dll有哪些方法以及方法的参数类型。直接贴这2个cs文件的代码，顺便解释和对比下：

对比大家就可以发现，只不过一个更加傻瓜化，参数都是Object了，其实这样反而不好，增加了类型转换的代价，如果知道，为何不给一个正确的给他呢。关于这2个dll的速度，曾经听说过是有差别的，博客园有人给过测试，我没实际测试过，还是习惯用传统的TestDemo.cs，因为参数类型都是Object，不直观，出了问题也有点头疼。
后面某些类或者方法的XML注释就不说了，自动生成的东西，可以对照M文件的注释来看。

上面这段信息主要是说明当前Matlab编译器的版本，因为编译的版本和部署的MCR版本必须对应起来，否则是不能运行的。然后有编译日期，以及编译的参数，类名以及M函数的地址等信息，其实知道这些参数，理论上是可以自己在程序里面调用Matlab的编译器进行编译工作的，只不过比较复杂，能力有限，研究不下去。下面的引用大家应该明白，这个是MWArray.dll里面的命名空间，所以混编的项目都要引用对应版本的MWArray.dll
1 static TestDemo() 2 { 3 if (MWMCR.MCRAppInitialized) 4 { 5 Assembly assembly= Assembly.GetExecutingAssembly(); 6 string ctfFilePath= assembly.Location; 7 int lastDelimiter= ctfFilePath.LastIndexOf(@"\"); 8 ctfFilePath= ctfFilePath.Remove(lastDelimiter, (ctfFilePath.Length - lastDelimiter)); 9 string ctfFileName = "PlotTest.ctf"; 10 Stream embeddedCtfStream = null; 11 String[] resourceStrings = assembly.GetManifestResourceNames(); 12 foreach (String name in resourceStrings) 13 { 14 if (name.Contains(ctfFileName)) 15 { 16 embeddedCtfStream = assembly.GetManifestResourceStream(name); 17 break; 18 } 19 } 20 mcr= new MWMCR("",ctfFilePath, embeddedCtfStream, true); 21 } 22 else 23 { 24 throw new ApplicationException("MWArray assembly could not be initialized"); 25 } 26 }
如果有一些C#的开发和编程经验看上面的代码问题应该不大，否则还真有点难说清楚，简单的说几个要点：
1）这个构造函数的作用主要是检测MCR对象是否初始化，如果没有，则寻找程序集，并拼接资源的位置，正确进行初始化
2) 上面的ctf其实是包含在dll程序集里面的，以资源的形式，这个文件是核心，它才真正的包括了Matlab编译之后的，MCR可以运行的中间程序。
3) 必须要合法正确的ctf文件和dll文件才能 正确的初始化mcr对象，合法的意思，是Matlab内部有校验机制，包括对相关版本，在以前的版本生成文件中，很明显，现在2012a里面都隐藏起来了，不过要求都一样。
4) 上面方法其实已经间接的告诉了我们怎么初始化mcr对象，有了mcr对象，一切都好办了，因为它才是MCR的核心。
1 public void PlotTest() 2 { 3 mcr.EvaluateFunction(0, "PlotTest", new MWArray[]{}); 4 } 5 public void PlotTest(MWArray n) 6 { 7 mcr.EvaluateFunction(0, "PlotTest", n); 8 } 9 public MWArray[] PlotTest(int numArgsOut) 10 { 11 return mcr.EvaluateFunction(numArgsOut, "PlotTest", new MWArray[]{}); 12 } 13 public MWArray[] PlotTest(int numArgsOut, MWArray n) 14 { 15 return mcr.EvaluateFunction(numArgsOut, "PlotTest", n); 16 }
看了字段代码，再对应mcr的初始化，其实都很明朗了。通过mcr的EvaluateFunction来调用M函数。上面的代码有几个重载方法，可以实用很多不同的情况，有时候，这些方法的个数会更多，其实没多大必要，也可以自己编译一下，把没用的删掉，保留少数几个有用的即可。同时也可以看到，这里直接通过字符串来传递函数名称的，因此必须保证这个函数能被mcr搜索到。比如我们这里的"PlotTest"这个函数其实就包含了ctf文件中（注意ctf文件是可以和dll分开的，在混编项目里可以设置）。
上述已经讲解了整个mcr调用的过程，其实就是通过mcr的EvaluateFunction来调用M函数，但要保证对于的函数名称在mcr搜索的范围内。那么我们是不是可以假设：内置函数都在MCR内部，应该是可以搜索到的，那么把上面的函数名称换一下，是不是也是可行的。这个假设也是我最早接触时候的想法，有了假设，当然要去验证。现在看来这个当然是肯定的，那么不妨重新演示一遍。过程不详细讲了，代码也有注释，混编要引用的MWArray.dll和命名空间也不提了，看代码：
1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Text; 5 using System.Reflection; 6 using System.IO; 7 8 using MathWorks.MATLAB.NET.Utility; 9 using MathWorks.MATLAB.NET.Arrays; 10 11 12 namespace BuildInFunctionDemo 13 { 14 class Program 15 { 16 static MWMCR mcr; 17 static void Main(string[] args) 18 { 19 #region 首先使用PlotTest.dll来初始化mcr,因为这个dll是混编“合法”产生的，只有这样才能顺利启动mcr 20 if (MWMCR.MCRAppInitialized) 21 { 22 string path = Path.Combine(System.Environment.CurrentDirectory, "PlotTest.dll"); 23 Assembly assembly = Assembly.LoadFile(path); 24 string ctfFilePath = assembly.Location; 25 int lastDelimiter = ctfFilePath.LastIndexOf(@"\"); 26 ctfFilePath = ctfFilePath.Remove(lastDelimiter, (ctfFilePath.Length - lastDelimiter)); 27 string ctfFileName = "PlotTest.ctf"; 28 Stream embeddedCtfStream = null; 29 String[] resourceStrings = assembly.GetManifestResourceNames(); 30 31 foreach (String name in resourceStrings) 32 { 33 if (name.Contains(ctfFileName)) 34 { 35 embeddedCtfStream = assembly.GetManifestResourceStream(name); 36 break; 37 } 38 } 39 mcr = new MWMCR("",ctfFilePath, embeddedCtfStream, true); 40 } 41 else 42 { 43 throw new ApplicationException("MWArray assembly could not be initialized"); 44 } 45 #endregion 46 47 #region 直接调用混编dll中的封装函数进行测试 48 mcr.EvaluateFunction(0, "PlotTest", 5); 49 50 //注意这里要断点调试才能看到效果哦，因为mcr会把图绘制在一个Figure上面， 51 //后面的会覆盖前面的，这里暂停一下，可以看前面的效果 52 //下面就是直接调用matlab的plot函数的效果 53 MWNumericArray x = new double[]{1,2,3,4,5}; 54 MWNumericArray y = new double[]{2,1,2.8,5.3,4.7}; 55 mcr.EvaluateFunction(0, "plot",x,y ); 56 #endregion 57 58 Console.ReadKey(); 59 } 60 } 61 }
唯一要注意的就是50-52的说明，要加断点看2次绘制的效果。分别截图如下：
