How to sort two lists? Sort distance

[cyrille de brébisson]

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...
