Transpose of matrix is one of the basic problem of mathematics . Since it is a problem of matrix then we should try to implement it . It is one of the most asked interview question so please prepare for this question .
Transpose Matrix :
When we flip one matrix over a diagonal then we get another matrix and that matrix is called transpose matrix .
So if our matrix is
A = { { 1 , 2 } , { 3 , 4 } }
Then transpose of our matrix will be
A(T) = { { 1 , 3 } , { 2 , 4 } }
Java Code :
public class Matrix
{
public static void transpose(int[][] mat)
{
for(int i=0;i<mat.length;i++)
{
for(int j=i+1;j<mat[i].length;j++)
{
int temp= mat[i][j];
mat[i][j]= mat[j][i];
mat[j][i]=temp;
}
}
}
public static void main(String [] args)
{
int [][] mat = { {1,2,3},{3,4,5},{7,2,0}};
System.out.println("------------------");
transpose(mat);
}
}
C++ Code :
#include<iostream>
public class Matrix
{
public static void transpose(int[][] mat , int row, int col)
{
for(int i=0;i<row;i++)
{
for(int j=i+1;j<col;j++)
{
int temp= mat[i][j];
mat[i][j]= mat[j][i];
mat[j][i]=temp;
}
}
}
}
int main()
{
int [][] mat = { {1,2,3},{3,4,5},{7,2,0}};
transpose(mat,3,3);
return 0;
}
