setdiff for multisets. multisetdiff(A,B) removes repeated elements of A only once for each time they occur in B.

Example:
multisetdiff([1,1,2,2],[1,1,2]) % returns 2

To work with cell arrays of strings or using the rows feature this version requires LEXCMP (see below). The current version does not work for non-string cell arrays (unless you have an implementation of SORT for cell arrays). Non-cell arrays can in principle be any objects for which SORT, SIGN, MINUS and comparison operations are defined.

See the help for more details.
