Hi, I have two monic polynomials U, V of equal degree d with integer coefficients. Furthermore the second one is of particularly simple form, namely with roots only at 0 and 1. I want to plot the value of their quotient in the range from 2 to 15.
Evaluating the quotient for any specific x in that range is no problem, but plotting usually fails with the message verbose 0 (2999: plot.py, generate_plot_points) WARNING: When plotting, failed to evaluate function at 200 points. verbose 0 (2999: plot.py, generate_plot_points) Last error message: '' Changing the number of plot_points does not help, so I tried to generate a minimal example for the mailing list. (My polynomials U and V are the result of a quite lengthy computation) d = 128 R = PolynomialRing(ZZ, x) U = x^d + R.random_element(d-1) V = x^d - x^(d-1) P = U/V P = P.simplify_full() G = P.plot(2, 15) G.show() Now, problems occur already earlier. The simplify_full exits with RuntimeError: maximum recursion depth exceeded and if I leave it out, the plotting fails with the same error. Is there something wrong in the way I use simplify_full or is this just not the way to plot such functions? Thanks, Konstantin PS: I run Sage Version 4.1.1 on OpenSUSE 11.1 from Emacs.
