将Fortran multiD数组转换为C++

#include <iostream>

void convertFortranToCpp(double* fortranArray, double** cppArray, int rows, int cols) {
    for (int i = 0; i < rows; i++) {
        for (int j = 0; j < cols; j++) {
            cppArray[i][j] = fortranArray[j * rows + i];
        }
    }
}

int main() {
    const int rows = 3;
    const int cols = 4;

    double fortranArray[rows * cols] = {1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0, 11.0, 12.0};
    double** cppArray = new double*[rows];
    for (int i = 0; i < rows; i++) {
        cppArray[i] = new double[cols];
    }

    convertFortranToCpp(fortranArray, cppArray, rows, cols);

    // 打印转换后的C++数组
    for (int i = 0; i < rows; i++) {
        for (int j = 0; j < cols; j++) {
            std::cout << cppArray[i][j] << " ";
        }
        std::cout << std::endl;
    }

    // 释放内存
    for (int i = 0; i < rows; i++) {
        delete[] cppArray[i];
    }
    delete[] cppArray;

    return 0;
