CVSROOT: /cvs/purrs Module name: purrs Changes by: zolo(a)cs.unipr.it 2002-09-08 13:02:15 Modified files: src : rr_solver.cc Log message: Fixed a bug in the function 'return_sum()' called by 'compute_symbolic_sum()': when we subtract to \p symbolic_sum the first terms in according to the order we must do q_k.subs(k == j) * alpha * pow(lambda, -1) instead of q_k.subs(k == j) * pow(lambda, -1). Improved also 'compute_symbolic_sum()' and 'subs_to_sum_roots_and_bases'. Patches: http://www.cs.unipr.it/cgi-bin/cvsweb.cgi/purrs/src/rr_solver.cc.diff?cvsro…
