if order is greater than one.

Modified files:
src : rr_solver.cc
Log message:
Rewrited the function 'solve_linar_constant_coeff()' and
'solve_order_2()': now in the case the roots are simple uses
'compute_symbolic_sum()'.

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'.
