| A compressed sparse version of LU_COPY is (currently) available in tests/cbs.cc. It reduces both the memory use, by computing the exact footprint prior to allocation, and saves time by avoiding operations involving the known zeroes. It also tweaks propagation rules a bit, still numerical results are identical to LU_COPY, by construction. | A compressed sparse version of LU_COPY is (currently) available in tests/cbs.cc.
