Dense matrices mod n via FFLAS/FFPACK

During last weeks Sage Days 32 I worked on finishing a patch by Clément Pernet and Burcin Eröcal which switches Sage’s native matrices mod n (for n<2^{23}) to FFLAS/FFPACK. The purpose of this exercise was to make operations with dense matrices mod n both faster and more memory efficient (currently, Sage does a lot of copying around when calling any LinBox function). Well, we almost succeeded. Continue reading “Dense matrices mod n via FFLAS/FFPACK”
