compute the symmetric difference of two MultiSets
symmdiff( M, N )
MultiSet; a MultiSet, set, or list
symmdiff( M, N ) returns the symmetric difference of M and N, which is (M union N) minus (M intersect N).
At least one argument must be a MultiSet for this routine to be invoked. Any other argument which is expected to be a MultiSet can be a MultiSet, a set or a list; in the latter two cases the argument is converted to a MultiSet before proceeding to evaluate this command. IsGeneralized(M) must return the same value for all MultiSet arguments M, and all non-MultiSet arguments will be promoted to MultiSets with this same property.
The MultiSet/symmdiff command was introduced in Maple 2016.
