CUDA arrays and c++ vectors

I'm new at CUDA and have the following question? My kernel is supposed to calculate a type:

vector <double *> *my_vector = new vector <double *>();

Before I tried to change the original c++ code to cuda it would calculate an array[6] in a loop and then push it back to my_vector.

for{
          //calculations


        double *array = new double[6];
        array[0] = data;
        array[1] = data;
        array[2] = data;
        array[3] = data;
        array[4] = data;
        array[5] = data;

        my_vector->push_back(array);
}

I know that using thrust could help but I prefer if I didn't use it. I thought of using a 2D array at my kernel and copying the data back to my host code and then copying that to my_vector with the std::vector. What I've tried so far has failed.

If anyone has some experience on this and has any idea it would be much help.

Look at the Thrust template library that provide useful templates for host and device code usage. The thrust::device_vector can be used like std::vector analogy, although not inside device code.
