-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all,
Is this the right place for suggestions for the function "solve" ? 1) The docstring has a typo : "... solve an equation of system ..." Should be an "or" here. 2) The section " solution_dict = True -- return a list of dictionaries containing the solutions. " made me think that solution_dict defaults to True which is not the case. Maybe this could be made more clear. 3) 'solution_dict = True' fails when only a single univariate equation is given. The solution is then not a list of lists and the conversion to dictionary fails: sage: var('a') a sage: solve ([a^2-1],a,solution_dict=True) - --------------------------------------------------------------------------- AttributeError Traceback (most recent call last) /home/tom/<ipython console> in <module>() /usr/local/sage/local/lib/python2.5/site-packages/sage/calculus/equations.pyc in solve(f, *args, **kwds) 1436 sol_list = string_to_list_of_solutions(a) 1437 if 'solution_dict' in kwds and kwds['solution_dict']==True: - -> 1438 sol_dict=[dict([[eq.left(),eq.right()] for eq in solution]) for solution in sol_list] 1439 return sol_dict 1440 else: AttributeError: 'SymbolicVariable' object has no attribute 'left' Thanks for your great work.
