一、保存csv数据

1.1 一维vector

#include <iostream>
#include <fstream>
#include <direct.h>
#include <io.h>
using namespace std;void Save_bias(vector<double> &bias, string names)
{string folderPath = "..//parameter_bias//" + names;if (0 != _access(folderPath.c_str(), 0)){_mkdir(folderPath.c_str());}ofstream pxData;pxData.open(folderPath + "//0.csv", std::ios::out | std::ios::trunc);for (int i = 0; i < bias.size(); i++){if (i == bias.size() - 1){pxData << bias[i] << std::endl;}else{pxData << bias[i] << ",";}}pxData.close();
}

1.2 二维vector

#include <iostream>
#include <fstream>
#include <direct.h>
#include <io.h>
using namespace std;void Save_means(vector<vector<double>> &means, string names)
{string folderPath = "..//parameter_mpvs//" + names;if (0 != _access(folderPath.c_str(), 0)){_mkdir(folderPath.c_str());}ofstream pxData;pxData.open(folderPath + "//0.csv", std::ios::out | std::ios::trunc);for (int i = 0; i < means.size(); i++){for (int j = 0; j < means[i].size(); j++){if (j == means[i].size() - 1){pxData << means[i][j] << std::endl;}else{pxData << means[i][j] << ",";}}}pxData.close();

二、读取csv数据

2.1 一维vector

#include <iostream>
#include <fstream>
using namespace std;void Read_bias(vector<double> &bias, string names)
{string folderPath = "..//parameter_bias//" + names;ifstream infile(folderPath + "//0.csv", ifstream::_Nocreate);string line, number;while (std::getline(infile, line)){istringstream is(line);vector<double> lineArray;while (std::getline(is, number, ',')){lineArray.push_back(atof(number.c_str()));}bias = lineArray;}
}

#include <iostream>
#include <fstream>
using namespace std;void Read_means(vector<vector<double>> &means, string names)
{string folderPath = "..//parameter_means//" + names;ifstream infile(folderPath + "//0.csv", ifstream::_Nocreate);string line, number;while (std::getline(infile, line)){istringstream is(line);vector<double> lineArray;while (std::getline(is, number, ',')){lineArray.push_back(atof(number.c_str()));}means.push_back(lineArray);}
}
