randsignal

<p>Optional argument corresponding to the largest eigenvalue of A (in magnitude).</p>

<p>Generate \(f = A^k x_{\eta} / r^k\),
with A the adjacency matrix and
\(x_{\eta}\) realization of Bernoulli random variables of parameter \(\eta\) and \(r\) the largest eigenvalue (in magnitude). The generation is carried out in sparse matrices in order to scale up.</p>

Provides the standard operations for signal processing on graphs:
graph Fourier transform, spectral graph wavelet transform,
visualization tools. It also implements a data driven method
for graph signal denoising/regression, for details see
De Loynes, Navarro, Olivier (2019) <arxiv:1906.01882>.
The package also provides an interface to the SuiteSparse Matrix Collection,
<https://sparse.tamu.edu/>, a large and widely used set of sparse matrix
benchmarks collected from a wide range of applications.
