修改下面的c++代码实现将结果存在3列的矩阵中matrixdouble row_major calc_micconst matrixdouble row_major& mat int threads 当样本量小于6个时终止程序 ifmatsize16 stdcerr error the number of data rows should be greater than 5 stdendl

#include #include <boost/numeric/ublas/matrix.hpp> #include <omp.h> #include "MINE.h"

using namespace boost::numeric::ublas;

// 计算每列两两之间的mic系数，并填充对称矩阵
omp_set_num_threads(threads);
#pragma omp parallel for

// 将结果存储在3列的矩阵中
