Cpp在多维向量中交换维度

#include <iostream>
#include <vector>

int main() {
    // 创建一个二维向量
    std::vector<std::vector<int>> matrix = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};

    // 打印原始矩阵
    std::cout << "原始矩阵：" << std::endl;
    for (const auto& row : matrix) {
        for (const auto& element : row) {
            std::cout << element << " ";
        }
        std::cout << std::endl;
    }

    // 交换维度
    std::vector<std::vector<int>> transposedMatrix(matrix[0].size(), std::vector<int>(matrix.size()));
    for (size_t i = 0; i < matrix.size(); ++i) {
        for (size_t j = 0; j < matrix[i].size(); ++j) {
            transposedMatrix[j][i] = matrix[i][j];
        }
    }

    // 打印交换维度后的矩阵
    std::cout << "交换维度后的矩阵：" << std::endl;
    for (const auto& row : transposedMatrix) {
        for (const auto& element : row) {
            std::cout << element << " ";
        }
