Hi list,
I am encountering a problem that I had some time before under Max and I have the same now that I switched to Pd (actually it's more a logical one than a soft one) Here it is : I am trying to retrieve the n last numbers of a float stream in order to sum them, and I want the n numbers to be refreshed every time a new value is coming (Like a hardware register does with bits) I tried several methods with spigot, glue, lists ... but nothing works. Either I get all the values refreshed all at the same time (n times the current value) or I lost values on the way. I also looked at data structures, it seems there is something to dig there but I am not familiar with data structures and I didn't succeed either. If anyone has an idea, a tip or a clue, it would be very helpful.
To be more descriptive here is what I would like to see :
At time n :
inlet (float at t(n))
|
Logical function
| | |
f(t(n)) f(t(n-1)) f(t(n-2)) ...
At time n+1 :
inlet (float at t(n+1))
|
Logical function
| | |
f(t(n+1)) f(t(n)) f(t(n-1)) ...
n.b. : f is for float and not the function !!!! ;) Of course, at initialisation only f(t(n)) would be non zero, but don't matter for now on.
Thx in advance
Sylvain

Ah, this is another job for the mighty power that has come to pd-0.39 with the [list] object family.
It only taketh two (2!) objects to solve this fine riddle.
I also added a dynamic setter for the register's size, however summing is left as an exercise for the reader.
