WebMar 14, 2024 · torch.fft.fft()是PyTorch中的一个函数，用于执行快速傅里叶变换(FFT)。它的参数包括input(输入张量)、signal_ndim(信号维度)、normalized(是否进行归一化)和dim(沿哪个维度执行FFT)。其中，input是必须的参数，其他参数都有默认值。 WebThe FFT of a real signal is Hermitian-symmetric, X [i] = conj (X [-i]) so the output contains only the positive frequencies below the Nyquist frequency. To compute the full output, use fft () Parameters. input ( Tensor) – the real input tensor. n ( int, optional) – Signal length.
