Real-to-complex Discrete Fourier Transform. Warning The function torch.rfft() is deprecated and will be removed in a future PyTorch release. Use the new torch.fft module functions, instead, by importing torch.fft and calling torch.fft.rfft() for one-sided output, or torch.fft.fft() for ...

Real to complex functions F.spectrogram,T.Spectrogram These functions return either real valued Tensor (power, energy) or complex valued Tensor (frequency representation), which depends on whatpowerargument was provided. Whenpoweris not provided, these functions return a complex-valued Tensor. In this...
具体来说,现在使用return_complex=False,会直接报错,但是要获得return_complex的效果,可以先用return_complex=True然后再使用torch.view_as_real()就可以了 举个例子,我使用了return_complex=False的效果: torch.stft(signal,n_fft=1024, hop_length=512, win_length=1024, return_complex=False).shape ...

复数 torch.complex64,torch.complex128 事实上就是来源于 C ,对于复数类型,还有 real, imag 方法获取实部和虚部 你可以这样使用以上参数值: x = torch.tensor([[1, 2, 3], [4, 5, 6]], dtype=torch.float64) y = torch.tensor([[1, 2, 3], [4, 5, 6]], dtype=torch.int64) print(x +...
The first tensor/array will be the real part of the new ComplexTensor and the second tensor/array will be the imaginary part. a = torch.randn(3,5) b = torch.randn(3,5) z = torchlex.ComplexTensor((a,b)) Converting a complex numpy array to a ComplexTensor: z_array = np....
