How to convert 3D matrix to 1D matrix ?

You have to do this 'manually' as there are no 'Copy' methods in the Array class which can deal with arrays of different dimensions. Here's an example:

using System;

class Test

{

static void Main()

{

int[,,] ia3d = new int[,,]

{

{ { 1, 2, 3 }, { 4, 5, 6} },

{ { 7, 8, 9 }, { 10, 11, 12 } }

};

int len1 = ia3d.GetLength(0);

int len2 = ia3d.GetLength(1);

int len3 = ia3d.GetLength(2);

int[] ia = new int[ia3d.Length];

for(int i = 0; i < len1; i++)

for(int j = 0; j < len2; j++)

for(int k = 0; k < len3; k++)

ia[i * len2 * len3 + j * len3 + k] = ia3d[i, j, k];

// check it worked

foreach(int i in ia) Console.WriteLine(i);

Console.ReadKey();

}
