Hi I'm trying to sum all the numbers that I'm going to write in array.

Because X-values range from 0 to 10000, I need something to automatically sum all the Y-values that ranges from -1000 to 1000.

I'm assuming that I have to use tabread object.

but I don't know how to continuously add the sequence of numbers.

For example if X-values are 0,1,2,3 and written Y-values are 10,20,30,40,
and if I put corresponding X-values into tabread object, It should firstly output 10, and then 30(10+20), and then 60(10+20+30), and then 100(10+20+30+40).

So, what I basically want is to automatically sum all the Y-values in array.

Somebody please help me!

The easy and fast way is to use [iem_tab/tab_sum].

Alternatively, you would use a counter to read through the array using [tabread] (see mod's tutorial if you aren't sure how to make one: http://puredata.hurleur.com/sujet-5880-simple-counters). The accumulator is simply a modified version of the counter in which the [+ ] and [f ] are switched, and you send numbers to [+ ] instead of bangs, of course.

Thank you Maelstorm!

You are truly a genius!!
