Multi-Scale Spectral Decomposition


Description

MSEIGS implements the Multi-Scale Spectral Decomposition algorithm, which is a fast eigensolver well-suited for approximating eigenpairs of large scale graphs, especially when the target rank is large.


Download

MSEIGS is written in C/C++ and comes with a Matlab mex interface.
