用Java转置矩阵
矩阵的转置是矩阵在其对角线上翻转,即矩阵的行索引和列索引被切换。一个例子如下:
Matrix =1 2 3
4 5 6
7 8 9
Transpose =
1 4 7
2 5 8
3 6 9
演示该程序的程序如下。
示例
public class Example {public static void main(String args[]) {
int i, j;
int row = 3;
int col = 2;
int arr[][] = {{2, 5}, {1, 8}, {6, 9} };
System.out.println("The original matrix is: ");
for(i = 0; i < row; i++) {
for(j = 0; j < col; j++) {
System.out.print(arr[i][j] + " ");
}
System.out.print("\n");
}
System.out.println("The matrix transpose is: ");
for(i = 0; i < col; i++) {
for(j = 0; j < row; j++) {
System.out.print(arr[j][i] + " ");
}
System.out.print("\n");
}
}
}
输出结果
The original matrix is:2 5
1 8
6 9
The matrix transpose is:
2 1 6
5 8 9
