did anyone work with C# and matlab?

the example below i found on the intetnet,it may offer you some help.

using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
Program p = new Program();
p.MatlabTest();
Console.WriteLine("press any key to exit...");
Console.ReadKey();
}
//test C# matlab invoke
private void MatlabTest()
{
Console.WriteLine("loading matlab for .NET liberary......");
DotNetTest.DotNetTestclass dt = new DotNetTest.DotNetTestclass();
Console.WriteLine("compelite......");
Console.WriteLine("-----------------------------------------------");

// multinomial
int demention = 3;
double[] dd = new double[demention];
dd[0] = 1;
dd[1] = 4;
dd[2] = 6;
//MathWorks.MATLAB.NET.Arrays.MWArray d =
//MathWorks.MATLAB.NET.Arrays.MWNumericArray.MakeSparse(
// 1, demention, MathWorks.MATLAB.NET.Arrays.MWArrayComplexity.Real, demention);
MathWorks.MATLAB.NET.Arrays.MWNumericArray d = (MathWorks.MATLAB.NET.Arrays.MWNumericArray)dd;
Console.WriteLine("begin to compute the multinomial:[{0}] ......", d.ToString());
// save the anwser
MathWorks.MATLAB.NET.Arrays.MWArray h;
//invoke matlab function to compute
h = dt.myroots(d);
// get the real part
Array real = ((MathWorks.MATLAB.NET.Arrays.MWNumericArray)h).ToArray(MathWorks.MATLAB.NET.Arrays.MWArrayComponent.Real);
string realpart = "real part list：";
foreach (double i in real)
{
realpart += i + "\t";
}
// get the imaginary part
Array imaginary = ((MathWorks.MATLAB.NET.Arrays.MWNumericArray)h).ToArray(MathWorks.MATLAB.NET.Arrays.MWArrayComponent.Imaginary);
string imaginarypart = "imaginary part list：";
foreach (double i in imaginary)
{
imaginarypart += i + "\t";
}
Console.WriteLine(realpart);
Console.WriteLine(imaginarypart);
// print results
Console.WriteLine("results:");
Console.WriteLine(h.ToString());
}
}
}
