Functions for taking the mean and standard deviation of an array of numbers?

I've been thinking about how to help Arduino users do more sophisticated analysis of their sensor data and this seems like a simple thing that could help with a bunch of things. There are some existing libraries for this (e.g. http://playground.arduino.cc/Main/Average) but it seems like mean() and standardDeviation() are common enough to be worth including in the core. What do you think?

Non vengono indicati file, test o punti di ingresso. Inizia esaminando l’organizzazione ArduinoCore-API e le API core esistenti, quindi determina l’interfaccia array appropriata, il comportamento numerico e i test necessari prima di decidere cosa comporterebbe un’aggiunta completa.
