使用与openmp C++并行的循环计算矩阵中每一行的最小值

#include <iostream>
#include <vector>
#include <limits>
#include <omp.h>

int main() {
    // 定义矩阵
    std::vector<std::vector<int>> matrix = {
        {5, 8, 3},
        {2, 9, 1},
        {4, 7, 6}
    };

    int num_rows = matrix.size();
    std::vector<int> min_values(num_rows, std::numeric_limits<int>::max());

    // 并行化循环计算每一行的最小值
    #pragma omp parallel for
    for (int i = 0; i < num_rows; ++i) {
        int min_val = std::numeric_limits<int>::max();
        for (int j = 0; j < matrix[i].size(); ++j) {
            if (matrix[i][j] < min_val) {
                min_val = matrix[i][j];
            }
        }
        min_values[i] = min_val;
    }

    // 打印每一行的最小值
    for (int i = 0; i < num_rows; ++i) {
        std::cout << "Row " << i << " minimum value: " << min_values[i] << std::endl;
    }

    return 0;
