Hi,
I'm having trouble to build a patch to measure the EUCLIDEAN DISTANCE between arrays (fiiled w/ audio data). I've started using expr~ to build the: pow($v2-$v1),2) but I couldn't make the 'sum' fction work in order to give the sum of the array N pts.

Attached is a PD patch ilustrating it.... Any help is appreciated,
Thanks!
