MultiSet/=

test if two MultiSets are equal

MultiSet/<>

test if two MultiSets are not equal

Calling Sequence

M = N

M <> N

Parameters

M

-

MultiSet; a MultiSet, set, or list

N

-

MultiSet; a MultiSet, set, or list

Description

• 

M = N constructs a boolean expression which tests if M and N are equal as MultiSets, under evaluation either explicity via evalb or implicitly as the test of a conditional, such as an if ... then ... end if statement.

• 

M <> N similarly tests for inequality of MultiSets.

• 

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/= and MultiSet/<> operators were introduced in Maple 2016.
