Transpose of a matrix in Java

Java program to find the transpose of a matrix (of any order), we interchange its rows and columns to obtain the transpose.

Matrix transpose in Java

import java.util.Scanner;

class TransposeAMatrix
{
  public static void main(String args[])
  {
    int m, n, c, d;

    Scanner in = new Scanner(System.in);
    System.out.println("Enter the number of rows and columns of matrix");
    m = in.nextInt();
    n = in.nextInt();

    int matrix[][] = new int[m][n];

    System.out.println("Enter elements of the matrix");

    for (c = 0; c < m; c++)
      for (d = 0; d < n; d++)
        matrix[c][d] = in.nextInt();

    int transpose[][] = new int[n][m];

    for (c = 0; c < m; c++)
      for (d = 0; d < n; d++)
        transpose[d][c] = matrix[c][d];

    System.out.println("Transpose of the matrix:");

    for (c = 0; c < n; c++)
    {
      for (d = 0; d < m; d++)
        System.out.print(transpose[c][d]+"\t");

      System.out.print("\n");
    }
  }
}

The program can be used to check if a matrix is symmetric or not. We compare a matrix with its transpose, if both are the same then it's symmetric otherwise non-symmetric. It's also useful for calculating the orthogonality of a matrix.
