C# Program to perform Matrix Transpose

You are Here:

Perform Matrix Transpose

In the following example, we will transpose the given matrix (two-dimensional array).

Example

C# Compiler
using System; namespace myApp { class Program { static void Main(string[] args) { int i, j, n; int[,] arr = { {1, 1, 1}, {2, 2, 2}, {3, 3, 3} }; Console.WriteLine("Matrix (3 x 3):"); for(i=0; i<3; i++) { for(j=0; j<3; j++) Console.Write("{0} ", arr[i, j]); Console.WriteLine(); } for(i=0; i<3; i++) { for(j=i+1; j<3; j++) { n = arr[i, j]; arr[i, j] = arr[j, i]; arr[j, i] = n; } } Console.WriteLine("\nMatrix Transpose:"); for(i=0; i<3; i++) { for(j=0; j<3; j++) Console.Write("{0} ", arr[i, j]); Console.WriteLine(); } } } }

Output

Matrix (3 x 3): 1 1 1 2 2 2 3 3 3 Matrix Transpose: 1 2 3 1 2 3 1 2 3

In the following example, we will get the values for (3 x 3) Matrix from the user and display the transpose matrix.

Example

C# Compiler
using System; namespace myApp { class Program { static void Main(string[] args) { int i, j, n; int[,] arr = new int[3, 3]; Console.WriteLine("Enter Matrix (3 x 3):"); for(i=0; i<3; i++) { for(j=0; j<3; j++) { Console.Write("a[{0}, {1}] = ", i, j); arr[i, j] = Convert.ToInt32(Console.ReadLine()); } } for(i=0; i<3; i++) { for(j=i+1; j<3; j++) { n = arr[i, j]; arr[i, j] = arr[j, i]; arr[j, i] = n; } } Console.WriteLine("\nMatrix Transpose:"); for(i=0; i<3; i++) { for(j=0; j<3; j++) Console.Write(arr[i, j] +" "); Console.WriteLine(); } } } }

Output

Enter Matrix (3 x 3): a[0, 0] = 1 a[0, 1] = 1 a[0, 2] = 1 a[1, 0] = 2 a[1, 1] = 2 a[1, 2] = 2 a[2, 0] = 3 a[2, 1] = 3 a[2, 2] = 3 Matrix Transpose: 1 2 3 1 2 3 1 2 3
