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
