I tried a lot to find a clear description about this issue but most of them do not cover my question.

How can I pass 2D array to function and receive it?

The following code is my MatLab function:

function V = Mfunction(f,U,A)
%  f is a vector 
%  A is a double number
%  u is a n x n matrix
%  output V is a n x n matrix
n = length(U);
for i=2:n+1
    for j=2:n+1
      U2(i,j) = U(i+1,j)/A;
    end
end
e = Mfunction(f,U2);
V = U + e;

This is my C# code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using MathWorks.MATLAB.NET.Arrays;
using MathWorks.MATLAB.NET.Utility;
using Mfunction;
namespace matlabApplication
{
    class Program
    {
        static void Main(string[] args)
        {
            int n = 100;
            double[,] U = new double[n, n];
            double[] f = new double[n];
              // some calculations such as follow
              for (int i = 1; i <= n; i++)
                {
                    for (int j = 1; j <= n; j++)
                    {
                       U[i,j] = U[i,j] + 10;
                       f[i,j] = U[i,j] * 10;
                    }
                }
              *// Now I need to pass f & U into the Matalb function
              // How?*
              MLApp.MLApp matlab = new MLApp.MLApp();
              matlab.Execute(@" cd C:\Users\jc262819\Documents\MATLAB");
              *// After calculation I need to save the output of Matlab function (V) in an array in c#
              // How?*
          }
      }
  }
