If I got a sequence of numbers coming out from my video tracking output x (I only want to compare x output and ignore y output) and I want to compare every 5 of them ...... In those 5 output numbers, I need to compare to each other and get the biggest one unless their difference are all under 5.

for example, there are 5 position tracking output in the first second: (2, 6, 4, 11, 13). In those 5 outputs, 13 is the biggest one so I only take 13 and continue to next 5 numbers. However, if the next 5 numbers are (5,4,7,6,8) then I will still keep 13 because in this set of numbers their difference are all not over 5 (even the biggest number 8 minus the most small number 4 is only 4).

I think what I can do is using counter to count 5 and get position x output in "somewhere" so that I can compare all of them at the same time. However, I don't know which object can let me store 5 different output and compare them at the same time. At logic part, I also have problems of how to compare all those 5 numbers all together. I don't know what is the best and most fast way to do the comparison. I would probably use "-", ">" and "if"....

Yes, I am a newbie so I know this question is very simple to most of you. Please help me out. I appreciate anyone who give me an direction.

The internet connection in my house is very weird right now. Here I try to post again. Sorry if I post two times.

you could use zl group, to get lists of 5 members, and then minimum and maximum objects, to get the extreme values. After that you compare them with an if object [if $i1 - $i2 > 5 then $i1 else bang], the bang is used to trigger the int out of a following int object....

I'd love to see an expr-based solution to this problem. Got one?

how about sorting the list of 5 numbers using Lsort (from the  
indispensable Lobjects by peter elsea),
substracting the first element from the last,
and if that is over 5,  then you replace the value you kept with the  
last element

this one is nearly an expr-based solution :)

it looks like it's a contest...

Thank you all. They are all working fine. I use zl to trigger a sequence of number and the result is all what I expect.

max(max((max($f1\,$f2))\,(max($f3\,$f4)))\,(max($f4\,$f5)));

Would you please tell me that's your logic expr really means? I just play around with it and I don't really know that is "" and "

max(max((max($f1\,$f2))\,(max($f3\,$f4)))\,(max($f4\,$f5)));

The backslash is used for special characters not to be interpreted as

In the example I gave you, the max (and min) functions in expr need 2

arguments, separated by a comma. You have to write it , or it does not work

expr max($i1,$i2) determines the maximum between i1 and i2.

expr max((max($i1,$i2)),(max($i3,$i4))) determines the maximum of the

maximum of i1 and i2 and the maximum of i3 and i4 (!!!!!), and so on...

For further infos about expr, have a look at tutorials 38, 48, 50.

Best.
