Hierarchically semi-separable (HSS) matrices are a type of structured matrix that arise in a range of scientific computing and engineering problems. Most notably, they have been used to develop novel direct and approximate high-performance solvers for linear systems. HssMatrices.jl provides HSS compression algorithms, arithmetic and visualisation tools. This allows Julia users to easily experiment with HSS matrices and corresponding algorithms.
I am planning to shortly introduce HssMatrices.jl and it's functions. Moreover, I will speak about the lessons learned from the implementation. You can find the package here:
