I'm looking to compare multiple numbers and getting the indexes of those equal to each other. I'm thinking a list-approach using [zl] objects is the fastest way to do it but I can't find a combination that works.

Any help would be greatly appreciated. If it's not possible with [zl] any other method is welcome as well. The numbers are coming in separately from multiple [counter]s. But I haven't been able to figure out any other method that's not going to be a mess of patch chords and a favela of objects.

What I'm hoping to do is something like:
Input: A A B A C D
Output (indexes): 1 2 4

the key is to collect repetitions into same coll line

using list items as coll indexes, and their list position index(es) as data

when coll dumps only lines with more than 1 item get collected into list

if you want to use zero based replace listfunnel 1 

for large lists one would maybe need to increase del 0 time

you asked indexing from 1 up.
if you want to use zero based replace listfunnel 1 
with listfunnel (defaults to zero)

P.S.
for large lists one would maybe need to increase del 0 time 


Damn, thank you :) I never would have arrived at this on my own.

I have some tinkering and picking it apart to fully understand what's happening but it's working.

Thank you so much :)

- send list to listfunnel to index the list items and reverse output pairs so that

- merge message to coll adds index(es) of each list item at same

coll address or index, so that if for example "A" is repeated 3 times in the list at list indexes 1 3 & 7

 which means that only if there were more than 1

occurences of a list item (repetitions), something would come out of second outlet of 

wipe leftovers from last list input before passing the list.

g is empty, nothing can trigger the join output

there is no mistery in that patch.

- send list to listfunnel to  index the list items and reverse output pairs so that
 list item is first, index second
-  merge message to coll adds index(es) of each list item at same
coll address or index, so that if for example "A" is repeated 3 times in the list at list indexes 1 3 & 7
A B A c d e A T
coll line becomes
A, 1 3 7 ;
- coll dump output runs through zl slice 1 which means that only if there were more than 1
 occurences of a list item (repetitions), something would come out of second outlet of 
zl slice 1

when that happens both outputs of zl slice 1 get combined into list
and appended to the list at the end.  
---------
few objects like
t b l clear set   or t l zlclear
wipe leftovers from last list input before passing the list.
if zl reg is empty, nothing can trigger the join output


Good topic, was just looking for something similar. Thank you.
