- **cmw (np.ndarray)**: Complex Morlet wavelet. - **cmwFFT (np.ndarray)**: Fourier transform of the wavelet. - **ssFFT (np.ndarray)**: Fourier transform of the input signal. - **nconv (int)**: Convolution length (signal + wavelet - 1). - **conv (np.ndarray)**: ...
# 2. Perform fourier convolution signal_fr = rfftn(signal, dim=-1) kernel_fr = rfftn(padded_kernel, dim=-1) 1. 2. 3. 3. 变换张量相乘 令人惊讶的是,这是我们功能中最复杂的部分。这有两个原因。(1) PyTorch 卷积运行于多维张量上,因此我们的 signal 和 kernel 张量实际上是三维的。从 PyTorch...
setigenprovides sample functions and shapes for each of these parameters. These all contribute to the final structure of the signal - the goal is to empower the user to generate artificial signals that are as simple or complex as one would like. ...
Trigger. This is the event that initiates a transition, the method that sends the signal to start a transition. Action. Specific operation or task that is performed when a certain state is entered, exited, or during a transition. The action is implemented through callbacks, which are functions...
Examples of linear dynamical systems include, but are not limited to, the Schrödinger equation that arises in quantum mechanics, the computational model for the signal propagation and interference in electric circuits, storm surge prediction models before an advancing hurricane, vibration analysis in ...
