Matrix-free construction of HSS representation using adaptive randomized sampling
Christopher Gorman, Gustavo Chávez, Pieter Ghysels +3
We present new algorithms for the randomized construction of hierarchically semi-separable matrices, addressing several practical issues. The HSS construction algorithms use a part…
