Calling Sequence

M subset N

Parameters

M

-

MultiSet; a MultiSet, set, or list

N

-

MultiSet; a MultiSet, set, or list

Description

• 

M subset N returns true if the multiplicity of each element of M is at most the multiplicity of the same element of 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.
