以下是必需的程序。
public class Tester { public static void main(String args[]) { int a[][] = { { 1, 3, 4 }, { 2, 4, 3 }, { 3, 4, 5 } }; int t[][] = new int[3][3]; //转置矩阵 for (int i = 0; i < 3; i++) { for (int j = 0; j < 3; j++) { t[i][j] = a[j][i]; } } System.out.println("原始矩阵:"); for (int i = 0; i < 3; i++) { for (int j = 0; j < 3; j++) { System.out.print(a[i][j] + " "); } System.out.println(); } System.out.println("转置矩阵:"); for (int i = 0; i < 3; i++) { for (int j = 0; j < 3; j++) { System.out.print(t[i][j] + " "); } System.out.println(); } } }
输出结果
原始矩阵: 1 3 4 2 4 3 3 4 5 转置矩阵: 1 2 3 3 4 4 4 3 5
