Greetings,
I'd like to construct a list as follows. Say I have a list of reals
{x1,x2,x3,...xn}, and another list of integers {r,s}. I'd like to
make a new list
{{x1,x1,x1,...},{x2,x2,x2....},{x3,x3,x3,...},....,{xn,xn,xn,...}},
where the first sublist is of length r, and the remaining sublists
are of length s.
Thanks,
-Mark
