The problem in the code

[codelover123hxy]

Hello, I read your code with respect,but have some question in the formula and code.In the original paper, the matrix of beta is [1,-1], but
in the function _orth，there is code that np.matrix([-1 * v[1], v[0]]).T,so I wander how the formula convert. I also need to expand the original model to three dimenstions. If you see my question, I hope we can communicate.Thank you!
