A question on LPD-Net details

[cloudcjf]

Hi, thanks for your pioneer work. I'm quite interested in LPD-Net and would like to go deep into the details. I found the formulation of the handcraft descriptors in your paper is just the opposite of those in your code. As NumPy lib sorts the eigenvalues from smallest to largest, eigen3d[0] is the smallest value. However, after I've double-checked with your paper and the paper you cite, eigen3d[0](the first eigenvalue) should be the largest one. Which one is correct? I'm quite confused now.
