PYthon For Homomorphic Encryption Libraries, perform encrypted computations such as sum, mult, scalar product or matrix multiplication in Python, with NumPy compatibility. Uses SEAL/PALISADE as backends, implemented using Cython. - ibarrond/Pyfhel
The filetorch_butterfly/special.pyshows how to construct butterfly matrices that performs FFT, inverse FFT, circulant matrix multiplication, Hadamard transform, and torch.nn.Conv1d with circular padding. The tests intests/test_special.pyshow that these butterfly matrices exactly perform those operatio...
