swissroll

Map the square $[0,1]^2$ in swiss roll
for all $x,y$ in $[0,1]^2$, set
$$Sx=\pi \sqrt{(b^2-a^2)x + a^2)}$$
$$Sy=\pi (b^2-a^2)y/2$$

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.
