Re: sort list


Hi,

  mysort[list_] := list[[Ordering[list[[All, 2]]]]]
or
  mysort[list_] := Sort[list, OrderedQ[{#1[[2]],#2[[2]]}]&]

should do the job:

  In = {{a, 2}, {b, 1}, {c, 3}} // mysort
  Out= {{b, 1}, {a, 2}, {c, 3}}


(You could also look for "Sort" in the online help...)

Regards,
Marcus
