RE: How to sort two lists?
Hello,
in Home, you can use the SORT(List, item in list to sort by) syntax. Sorry, but the help for SORT does not seem to have been updated... Anyhow, SORT now takes 2 parameters, the list to sort and one or more sequence of sort indexes... assuming that L1 is a list of lists. so, SORT(L1, a) sorts by element a of the sub lists SORT(L1, {a, b, c}) sorts by element a, then b, then c of the sub list (b is used if elements a are equal...) you can even do SORT(L1, {{a, b, c}, d}) in this case {a, b, c} means sort L1 by the element (a, b, c) of L1, is recall cth element of the bth list of the ath list of L1! ie, the {a, b, c}, follows the same rules as L1(parameters)... you can of course use this, to sort by nth element in matrices in lists and the like... Cyrille Although I work for the HP calculator group, the views and opinions I post here are my own. I do not speak for HP.
