c++ 计算心率数据的几个算法

**计算心率数据的几种算法**

心率是指人体在单位时间内的心跳次数，通常以每分钟（bpm）为单位。计算心率数据对于运动员、医生和研究人员来说非常重要，可以帮助他们评估身体状况、监测健康指标等。在 C++ 中，我们可以使用以下几种算法来计算心率数据：

###1. 平均值法平均值法是最简单的方法之一。我们只需要将所有的心跳数据取平均即可。

cpp#include <iostream>
#include <vector>

// 心率数据结构体struct HeartRateData {
 int time; // 时间（秒）
 int heartRate; // 心率（bpm）
};

int main() {
 std::vector<HeartRateData> data = {{1,60}, {2,62}, {3,61}, {4,63}, {5,62}};

 int sum =0;
 for (const auto& d : data) {
 sum += d.heartRate;
 }

 double averageHeartRate = static_cast<double>(sum) / data.size();
 std::cout << "平均心率：" << averageHeartRate << " bpm" << std::endl;

 return0;
}

cpp#include <iostream>
#include <vector>

// 心率数据结构体struct HeartRateData {
 int time; // 时间（秒）
 int heartRate; // 心率（bpm）
};

int main() {
 std::vector<HeartRateData> data = {{1,60}, {2,62}, {3,61}, {4,63}, {5,62}};

 double sum =0.0;
 for (const auto& d : data) {
 sum += static_cast<double>(d.heartRate);
 }

 int windowSize =3; // 移动平均窗口大小 double averageHeartRate =0.0;

 for (int i =0; i <= data.size() - windowSize; ++i) {
 double sumWindow =0.0;
 for (int j = i; j < i + windowSize; ++j) {
 sumWindow += static_cast<double>(data[j].heartRate);
 }
 averageHeartRate = sumWindow / windowSize;
 }

 std::cout << "移动平均心率：" << averageHeartRate << " bpm" << std::endl;

 return0;
}

cpp#include <iostream>
#include <vector>

// 心率数据结构体struct HeartRateData {
 int time; // 时间（秒）
 int heartRate; // 心率（bpm）
};

int main() {
 std::vector<HeartRateData> data = {{1,60}, {2,62}, {3,61}, {4,63}, {5,62}};

 int minHeartRate = data[0].heartRate;
 for (const auto& d : data) {
 if (d.heartRate < minHeartRate) {
 minHeartRate = d.heartRate;
 }
 }

 std::cout << "最小心率：" << minHeartRate << " bpm" << std::endl;

 return0;
}

cpp#include <iostream>
#include <vector>

// 心率数据结构体struct HeartRateData {
 int time; // 时间（秒）
 int heartRate; // 心率（bpm）
};

int main() {
 std::vector<HeartRateData> data = {{1,60}, {2,62}, {3,61}, {4,63}, {5,62}};

 int maxHeartRate = data[0].heartRate;
 for (const auto& d : data) {
 if (d.heartRate > maxHeartRate) {
 maxHeartRate = d.heartRate;
 }
 }

 std::cout << "最大心率：" << maxHeartRate << " bpm" << std::endl;

 return0;
}

cpp#include <iostream>
#include <vector>

// 心率数据结构体struct HeartRateData {
 int time; // 时间（秒）
 int heartRate; // 心率（bpm）
};

int main() {
 std::vector<HeartRateData> data = {{1,60}, {2,62}, {3,61}, {4,63}, {5,62}};

 std::sort(data.begin(), data.end());

 int size = data.size();
 if (size %2 ==0) {
 int mid1 = data[size /2 -1].heartRate;
 int mid2 = data[size /2].heartRate;
 int medianHeartRate = (mid1 + mid2) /2;
 std::cout << "中位数心率：" << medianHeartRate << " bpm" << std::endl;
 } else {
 int medianHeartRate = data[size /2].heartRate;
 std::cout << "中位数心率：" << medianHeartRate << " bpm" << std::endl;
 }

 return0;
}
