Java转置矩阵的程序
将矩阵的行转换为列并将矩阵的列转换为行称为矩阵的转置。
让我们看看一个简单的示例，将3行3列的矩阵转置。
public class MatrixTransposeExample{
public static void main(String args[]){
//creating a matrixint original[][]={
{1,3,4},
{2,4,3},
{3,4,5}
};
//creating another matrix to store transpose of a matrixint transpose[][]=new int[3][3];
//3 rows and 3 columns
//Code to transpose a matrixfor(int i=0;i<3;i++){
for(int j=0;j<3;j++){
transpose[i][j]=original[j][i];
}
}
System.out.println("Printing Matrix without transpose:");
for(int i=0;i<3;i++){
for(int j=0;j<3;j++){
System.out.print(original[i][j]+" ");
}
System.out.println();
//new line }
System.out.println("Printing Matrix After Transpose:");
for(int i=0;i<3;i++){
for(int j=0;j<3;j++){
System.out.print(transpose[i][j]+" ");
}
System.out.println();
//new line }
}
}
输出:
Printing Matrix without transpose:
1 3 4
2 4 3
3 4 5
Printing Matrix After Transpose:
1 2 3
3 4 4
4 3 5
用于显示转置矩阵的Java程序
让我们再来看一个显示矩阵转置的示例。在这里，我们不会创建另一个矩阵。
public class MatrixTransposeExample2{
public static void main(String args[]){
//creating a matrixint original[][]={
{1,3,4},
{2,4,3},
{3,4,5}
};
System.out.println("Printing Matrix without transpose:");
for(int i=0;i<3;i++){
for(int j=0;j<3;j++){
System.out.print(original[i][j]+" ");
}
System.out.println();
//new line }
System.out.println("Printing Matrix After Transpose:");
for(int i=0;i<3;i++){
for(int j=0;j<3;j++){
System.out.print(original[j][i]+" ");
}
System.out.println();
//new line }
}
}
输出:
Printing Matrix without transpose:
1 3 4
2 4 3
3 4 5
Printing Matrix After Transpose:
1 2 3
3 4 4
4 3 5
用于转置矩阵的Java程序(另一种方式)
您还可以使用未预定义矩阵值的方法。在这里，用户必须将值作为输入。
import java.util.Scanner;
public class MatrixTransposeExample2 {
public static void main(String args[]) {
int i, j;
System.out.println("Enter total rows and columns: ");
Scanner s = new Scanner(System.in);
int row = s.nextInt();
int column = s.nextInt();
int array[][] = new int[row][column];
System.out.println("Enter matrix:");
for(i = 0;i <row;i++) {
for(j = 0;j <column;j++) {
array[i][j] = s.nextInt();
System.out.print(" ");
}
}
System.out.println("The above matrix before Transpose is ");
for(i = 0;i <row;i++) {
for(j = 0;j <column;j++) {
System.out.print(array[i][j]+" ");
}
System.out.println("");
}
System.out.println("The above matrix after Transpose is ");
for(i = 0;i <column;i++) {
for(j = 0;j <row;j++) {
System.out.print(array[j][i]+" ");
}
System.out.println("");
}
}
}
