Using Matlab DLL in C# and the problem of converting arrays

I have a piece of code in Matlab and convert it to dll file to use in C#.

if true
  MWNumericArray arr1 = teee;   % n by 1
  MWNumericArray arr2 = Bx;     % n by 1
  MWNumericArray arr0 = CoefAx; % n by n array
  amgClass aobj = new aClass();
  MWArray resultA = aobj.A((MWArray)arr0, (MWArray)arr2, (MWArray)arr1, 3, 2, 1, 1, 200, 0.000001, 2, 0.25);
end

The error I am getting is about the dimension of matrix which exceed in the code. I check the matlab code with matlab data and it works.

The only thing I feel can be a problem is about input dimensions.

C# 1D arrays are like : 1 by n but in Matlab they are like: n by 1

How can I change this arrangement? Any comments?

Thank you.
