Hi all, We are pleased to present FLINT version 2.2.
It is available for download at our website (http://www.flintlib.org/): Source: http://www.flintlib.org/flint-2.2.tar.gz Documentation: http://www.flintlib.org/flint-2.2.pdf (165 pp.) Contributors: Fredrik Johansson, Sebastian Pancratz, William Hart, with bug reports by Serge Torres. For those after the benchmarketing figures, please see: http://sage.math.washington.edu/home/fredrik/flint/timings.html My personal favourite is determinant of a 10x10 matrix with random rational coefficients of 100 bits: Sage / flint2 11 mins 50 s 4.2 milliseconds This release contains some fantastic new modules: fmpq -- multiple precision rational numbers fmpq_mat -- matrices over QQ fmpz_poly_mat -- matrices over Z[x], i.e. polynomial matrices fmpz_poly_q -- rational functions over Q (quotients of integer polynomials) padic -- padic numbers Although they are already fairly developed modules, they are still considered under development (especially the padic module). Some interface changes are still possible in the future. There have also been numerous new functions and improvements made in the fmpz_mat, longlong, nmod_mat, arith, fmpz, fmpz_vec, fmpz_poly, nmod_poly and mpn_extras modules and some build fixes. Full details can be found at the bottom of the NEWS file: https://github.com/fredrik-johansson/flint2/blob/trunk/NEWS The following functionality from flint 1.5 is yet to be ported to the flint 2.x series: nmod_poly_gcd_hgcd -- asymptotically fast gcd nmod_poly_factor_berlekamp -- Z/nZ[x] factorisation nmod_poly_factor_cantor_zassenhaus -- Z/nZ[x] factorisation fmpz_poly_mul_SS -- fast Z[x] multiplication for large coefficients and medium to large lengths some FFT precaching and middle product functions for nmod_poly_div_newton -- faster Z/nZ[x] division It is expected that this functionality will be completed over the next 2-3 flint releases.
