如何将特征矩阵转换为C/C++数组

#include <iostream>

// 将特征矩阵转换为C/C++数组
void convertFeatureMatrixToCArray(double** featureMatrix, int rows, int cols, double* cArray) {
    for (int i = 0; i < rows; i++) {
        for (int j = 0; j < cols; j++) {
            cArray[i * cols + j] = featureMatrix[i][j];
        }
    }
}

int main() {
    // 假设特征矩阵的大小为3行4列
    int rows = 3;
    int cols = 4;
    
    // 创建特征矩阵
    double** featureMatrix = new double*[rows];
    for (int i = 0; i < rows; i++) {
        featureMatrix[i] = new double[cols];
    }
    
    // 初始化特征矩阵
    for (int i = 0; i < rows; i++) {
        for (int j = 0; j < cols; j++) {
            featureMatrix[i][j] = i * cols + j + 1;
        }
    }
    
    // 创建C/C++数组
    double* cArray = new double[rows * cols];
    
    // 将特征矩阵转换为C/C++数组
    convertFeatureMatrixToCArray(featureMatrix, rows, cols, cArray);
    
    // 打印C/C++数组
    for (int i = 0; i < rows * cols; i++) {
        std::cout << cArray[i] << " ";
    }
    std::cout << std::endl;
    
    // 释放内存
    for (int i = 0; i < rows; i++) {
        delete[] featureMatrix[i];
    }
    delete[] featureMatrix;
    delete[] cArray;
    
    return 0;
}
