How to compare 4 streams of numbers
hello,
i need to compare 4 continuous streams of numbers and count exactly how many times one of the streams (either the 1st,2nd,3rd or 4th) put out the smallest value of all.
I cannot figure out how to do it without faulty results in counting.
Any ideas?
Regards
hi elden,
I stumbled across your post while browsing the forum, and I have an abstraction that gives the min of 4 numbers AND the position (1-4) of the smaller one in the list.
Maybe it's useful for what you want? You could put a [sel 1 2 3 4] after it and count the bangs for each match.
Hope it helps.
Thanks Guilherme,
sorry for the delay - I've been into other stuff for quite a long time. Regarding your patch: If I feed it 4 streams of numbers, the results are often wrong! I don't know - maybe I did something wrong? Could you check out this edited patch? Or do I need to feed your expressions a "List"?
Regards
in pd almost every object needs to receive from right to left order over it's inlets (the first inlet needs to be the last triggered in order to get the numbers together). the trigger object will output from it's outlets from right to left with any type (see it's help file).
or unpack would output from right to left if you did have it as a list
I knew I missed anything...I'll check that out and give feedback, if it works or not. Thanks!
Hi elden,
sebfumaster is right, it's the order in which you're sending your values that is the issue. Without a [trigger] object or an [unpack], they're sent in the order in which you created the connections (here: from left to right, the opposite of what we'd want). Obviously this is very hard to keep track of, whence the objects that force this order for us.
If you put a [t b b b b] between your [bng] and the [random]s, which each of those connected to an output of the former, it should do the trick.
had the same problem. big help, thanx.
theres also a helpful tutorial on this now http://puredata.hurleur.com/sujet-6381-hot-cold-inlets-execution-order-trigger
Hey everyone, I stumbled upon this trying to find a way to compare 12 streams of numbers and it's great! I tried to adjust it so it works for 12 streams of numbers, and so far it works. The only thing I'm having trouble with is the position of the minimum number that it outputs, and I know why it's not showing it correctly but I can't seem to find a way to fix it.
I'll attach my patch, if anyone knows how it could be done I would appreciate it!
bump....
anyone??
heres a modified list-minmax from list-abs that includes a counter. This way it will work with any number of numbers in a list.
Oops! Looks like something went wrong!
