%description
Graph signals residing on the vertices of a graph have recently gained
prominence in research in various fields. Many methodologies have been
proposed to analyze graph signals by adapting classical signal processing
tools. Recently, several notable graph signal decomposition methods have
been proposed, which include graph Fourier decomposition based on graph
Fourier transform, graph empirical mode decomposition, and statistical
graph empirical mode decomposition. This package efficiently implements
multiscale analysis applicable to various fields, and offers an effective
tool for visualizing and decomposing graph signals. For the detailed
methodology, see Ortega et al. (2018) <doi:10.1109/JPROC.2018.2820126>,
