Solving boundary value problems using the shooting method
The boundary value problems require information at the present time and a future time. We will see how we can use shooting method to solve problems where we ...
Efficiently compute spectrogram for large dataset in python
Librosa can efficiently compute the spectrogram for large time series data in seconds. We will use that to plot the spectrogram using matplotlib
