WebSpectrograms can be used as a way of visualizing the change of a nonstationary signal’s frequency content over time. Parameters: xarray_like. Time series of measurement values. fsfloat, optional. Sampling frequency of the x time series. Defaults to 1.0. windowstr or tuple or array_like, optional. Desired window to use. Webto conform with Python’s array indexing convention. We shall assume open boundary condi-tions. Code Analysis—Let us now build and diagonalise H using QuSpin. First, we load the re-quired Python packages.

Given a set of data points X = [x1, …, xn] ∈ ℝp × n, where n is the number of samples and p is the dimensionality of the data, spectral clustering (SC) uses the similarity matrix S = (sij) ∈ ℝn × n, where sij ≥ 0 represents a measure of the similarity between data points xi and xj.
