Hi all,

I'm trying to count the number of times a value surpasses a given value.
This is roughly what I had in mind:


but it doesn't work (why else would I call for help with you guys) :)

On a related note I also want to count the number of samples I'm dealing


but I always get a NaN if I gprint out the samples variable.

BTW isn't there another way to do :


because adding the val,POP trick is a bit annoying...

Anyhow, I hope to stir up some thoughts and maybe discuss some options,
solutions, ...

thanks in advance,
Christophe VG
