输入矩阵的行和列以及矩阵各个元素，输出它的转置矩阵。 C语言：
#include <stdio.h> int main() { int line, colums; printf("输入矩阵行列\n"); scanf("%d%d", &line, &colums); int array[line][colums]; for(int i = 0;i < line;i++) for(int j = 0;j < colums;j++) scanf("%d", &array[i][j]); printf("\n原矩阵\n"); for(int i = 0;i < line;i++){ for(int j = 0;j < colums;j++) printf("%d ", array[i][j]); printf("\n"); } printf("\n转置矩阵\n"); for(int j = 0;j < colums;j++){ for(int i = 0;i < line;i++) printf("%d ", array[i][j]); printf("\n"); } return 0; } /* Code Running Results 输入矩阵行列 2 3 1 2 3 4 5 6 原矩阵 1 2 3 4 5 6 转置矩阵 1 4 2 5 3 6 */以下 C++ 的代码与 C语言 几乎是一样的，是一样的道理，都是使用二维数组来实现矩阵的转置，只是输入输出换了一种编写方式。 C++:
#include <iostream> using namespace std; int main() { int line, colums; cout<<"输入矩阵行列"<<endl; cin>>line>>colums; int array[line][colums]; for(int i = 0;i < line;i++) for(int j = 0;j < colums;j++) cin>>array[i][j]; cout<<endl<<"原矩阵"<<endl; for(int i = 0;i < line;i++){ for(int j = 0;j < colums;j++) cout<<array[i][j]<<" "; cout<<endl; } cout<<endl<<"转置矩阵"<<endl; for(int j = 0;j < colums;j++){ for(int i = 0;i < line;i++) cout<<array[i][j]<<" "; cout<<endl; } return 0; } /* Code Running Results 输入矩阵行列 2 3 1 2 3 4 5 6 原矩阵 1 2 3 4 5 6 转置矩阵 1 4 2 5 3 6 */Java 自然也可以使用二维数组实现矩阵的转置，但是那样大可不必再重复一遍。 可以换一种方式，把二维数组换成存放数组列表的数组列表 ( 即 ArrayList<ArrayList> ) 。 Java:
import java.util.ArrayList; import java.util.Scanner; public class TestTwo extends Thread{ public static void main(String[] args) { Scanner sc = new Scanner(System.in); System.out.println("请输入矩阵行列"); int line = sc.nextInt(); int colums = sc.nextInt(); ArrayList<ArrayList<Integer>> arraylistline = new ArrayList<ArrayList<Integer>>(); for(int i = 0;i < line;i++) { ArrayList<Integer> arraylistcolumns = new ArrayList<Integer>(); for(int j = 0;j < colums;j++) arraylistcolumns.add(sc.nextInt()); arraylistline.add(arraylistcolumns); } System.out.println("原矩阵"); for(int i = 0;i < line;i++) System.out.println(arraylistline.get(i)); System.out.println("\n转置矩阵"); ArrayList<Integer> transposematrix = new ArrayList<Integer>(); for(int j = 0;j < colums;j++) { for(int i = 0;i < line;i++) transposematrix.add(arraylistline.get(i).get(j)); System.out.println(transposematrix); transposematrix.clear(); } sc.close(); } } /* Code Running Result 请输入矩阵行列 2 3 1 2 3 4 5 6 原矩阵 [1, 2, 3] [4, 5, 6] 转置矩阵 [1, 4] [2, 5] [3, 6] */接下来就要提现 Python 的强大了 Python3:
matrix = [] print("请输入矩阵行列") line = int(input()) colums = int(input()) for x in range(line): row = [] for y in range(colums): temp = int(input()) row.append(temp) matrix.append(row) print("原矩阵") row = [] for row in matrix: print(row) print("转置矩阵") row = [] transposed = [[row[i] for row in matrix] for i in range(colums)] # 矩阵转置 for row in transposed: print(row) #Code Running Result # 2 # 3 # 1 # 2 # 3 # 4 # 5 # 6 # [1, 2, 3] # [4, 5, 6] # [1, 4] # [2, 5] # [3, 6]transposed = [[row[i] for row in matrix] for i in range(colums)]
仅用了这一行就实现了矩阵的转置
