Release 1.7.5
by Richard B. Kreckel 17 Feb '19

17 Feb '19

Hi, A new GiNaC version has just been released. The changes are: * Add Markowitz-ordered Gaussian elimination. * Avoid un-normal zeros in matrix::solve(). * Accept exprseq arguments in lsolve(eqns, vars). * Add overload of matrix::rank(solve_algo). * Fix case in G_do_hoelder with real x values which are not cl_R. * Fix an elusive bug in expairseq/add ctor, introduced in 1.7.0. Happy hacking! -richy.
