In the previous post, written code for matrix multiplication, in the current post, we will a write a java code to transpose a given matrix. The transpose of matrix is to interchange the rows and columns for the given matrix.

Example:-

The below code is the source code of java program to transpose of a given matrix,

Example:-

Transpose of Matrix |

The below code is the source code of java program to transpose of a given matrix,

*MatrixTranspose.java,*```
package com.example.demo;
public class MatrixTranspose {
public static void main(String[] args) {
int matrix[][] = {{1,2,3,4},{5,6,7,8},{9,10,11,12}};
int m = 3; //no. of rows
int n = 4; //no. of columns
System.out.println("Matrix before transpose is - ");
```

```
for (int i = 0; i < m; i++) {
for (int j = 0; j < n; j++) {
System.out.print(matrix[i][j]+" ");
}
System.out.println(" ");
}
int transMatrix[][] = new int[n][m];
System.out.println("Matrix after transpose is - ");
```

```
for (int i = 0; i < n; i++) {
for (int j = 0; j < m; j++) {
transMatrix[i][j] = matrix[j][i];
System.out.print(transMatrix[i][j]+" ");
}
System.out.println(" ");
}
}
}
```

*Output:--*Matrix before transpose is -

1 2 3 4

5 6 7 8

9 10 11 12

Matrix after transpose is -

1 5 9

2 6 10

3 7 11

4 8 12
