Summing multiple arrays


Hi guys, Hoping someone can help with this one please…

I am multiple arrays which all have the same structure, but different names.

So for example, I have:

abc[name, class, height]
def[name, class, height]
xyz[name, class, height]

How would I sum all the heights?




extract the heights, sum them up. Cf.,


or array_column


Perfect! array_column will get the job done, thank you!
