Use of FFT (Fast Fourier Transofrom) in CKKS Scheme

[Rahn80643]

Question

Whether CKKS scheme uses FFT

Further Information

Hi all,
Does CKKS scheme in module tenseal make of FFT for accelerating the computation? There is an implementation in sealapi that sets using_fft but no similar functions in tenseal module.

Screenshots

In tests/python/sealapi/test_context.py, using_fft can be verified.

If applicable, add screenshots to help explain your question.
