WebJan 26, 2024 · because scipy.sparse matrices follow the numpy.matrix convention of treating the multiplication operator as a matrix product. So when you pass two numpy.ndarray objects to this function, you're effectively calling x * x.T, which is a broadcasted outer product and thus produces a 2x2 result.. So this isn't a bug, but rather …
