Function Documentation

inline Tensor torch::fft::ihfft2(const Tensor &self, at::OptionalIntArrayRef s = std::nullopt, IntArrayRef dim = {-2, -1}, std::optional<c10::string_view> norm = std::nullopt)

Computes the 2-dimensional IFFT of a real input signal.

The output is a onesided representation of the Hermitian symmetric time domain signal. See https://pytorch.org/docs/main/fft.html#torch.fft.ihfft2.

Example:

auto T = torch::randn({128, 128}, torch::kDouble);
auto t = torch::fft::hfft2(T);
assert(t.is_complex() && t.size(1) == 65);
