[fricas-devel] improved seriesSolve

2010-01-05 Thread Martin Rubey
currently seriesSolve uses a power series Ansatz of the form f(x) = f_0 + f_1 x + ... + f_k x^k + \sum_{n>k} a x^n (assuming that f_0, f_1, ..., f_k are already known) and solves for a. This works surprisingly well, but of course not always. The patch attached fixes this, please give OK to commi
