在C#中调用Matlab, 需要先配置一下Matlab编译器, 然后在VS里面引用Matlab组件
具体操作如下:

在VS里面引用Matlab组件
引用   .Net MWArray API (不是必须)
引用Matlab Application Type Library


using MathWorks;
using MathWorks.MATLAB;
using MathWorks.MATLAB.NET.Arrays;
using MathWorks.MATLAB.NET.Utility;
using MLApp;
private void button1_Click(object sender, EventArgs e)
    {
        MLApp.MLAppClass matlab = new MLApp.MLAppClass();
        string command;
        command = "t=2:0.2:4*pi;y=sin(t);plot(t,y)";
      
        matlab.Visible = 1;         
        matlab.Execute(command);     // 执行Matlab命令
        command = @"print(gcf,   '-djpeg',   'c:\Test1')";     // 保存图片
        matlab.Execute(command);
        matlab.Quit();
        matlab = null;
        pictureBox1.Image = Image.FromFile(@"c:\Test1.jpg");   
    }


以上网上转载的用c#调用matlab的另外一种方法，为什么用lm算法训练BP网络的代码运行时就不能跳出仿真图，换其他函数就都可以。各位高手帮忙指点下迷津。
private void Form1_Load(object sender, EventArgs e)
    {
        MLAppClass matlab = new MLAppClass();
        string command = "P=[21 23;12 43;23 15;]" +
        "I=[12;23;45];" +
        "P=P';" +
        "I=I';" +
        "save data P I;" +
        "[Pn,minp,maxp,In,mint,maxt] = premnmx(P,I)" +
    
        "net=newff(minmax(Pn),[10,1],{'tansig', 'purelin'},'trainbr');" +
      
        "net=init(net)" +
        "net.trainParam.show=100; %两次显示之间的训练步数" +
        "net.trainParam.lr=0.3;%学习速率" +
        "net.trainParam.epochs=10000; %训练次数" +
        "net.trainParam.goal=0.000001;%训练目标" +
        "[net,tr]=train(net,Pn,In);" +
        "Inputweights=net.IW{1,1}" +
        "Inputbias=net.b{1}" +
        "Layerweights=net.LW {2,1}" +
        "Layerbias=net.b{2}"+
          "figure(gcf)";

        matlab.Visible = 1;
        matlab.Execute(command);
        matlab.Quit();
        matlab = null;
        }
  }
