If you always give a list of Expr and the symbols you want you e.g.
solve(list(eqs), list(syms)) you will get
- a single dictionary if it's linear
- a list of tuples if it's non-linear
- None if there is no solution
- an error if no subset of symbols gave a solution
perhaps something like this would work...
def canonical_solve(eqs, syms):
assert iterable(eqs) and is_sequence(syms)
syms = list(syms)
syms.append(Dummy()) # force dict output
return solve(eqs, *syms) or {}
/c
