在C#中調用Matlab, 需要先配置一下Matlab編譯器, 然后在VS里面引用Matlab組件
具體操作如下:

在VS里面引用Matlab組件
引用 ??.Net MWArray API (不是必須)
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); ????// 執行Matlab命令
????????command = @"print(gcf, ??'-djpeg', ??'c:\Test1')"; ????// 保存圖片
????????matlab.Execute(command);
????????matlab.Quit();
????????matlab = null;
????????pictureBox1.Image = Image.FromFile(@"c:\Test1.jpg"); ??
????}


以上網上轉載的用c#調用matlab的另外一種方法，為什么用lm算法訓練BP網絡的代碼運行時就不能跳出仿真圖，換其他函數就都可以。各位高手幫忙指點下迷津。
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)" +

??????????"figure(gcf)";

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