Re: setunion() on a vector of sets

Dear Bill,

Thank you for the pointer to fold(). 

I think it'd still be beneficial (and uniform in view of other functions) to provide the syntax setunion(x,{y}).

Regards,

Max

You can use fold:

? fold(setunion,[[1,2,3],[2,3,4],[4,5,6]])
%2 = [1,2,3,4,5,6]

Cheers,
Bill.
