Hello
i got a a couple of different sized arrays of ptnumbers that i want to combine into one array to access them later


---
if i run the above code i get {0,0,0} as contents of the array
I guess that has to do with my declaration as i@

---

I can write them all into array as one with append in
long list {1,2,3,4,5,6,7,8,9}

but i want to keep them
seperate as arrays( {{1,2,3}, {4,5,6,7}, {8,9,10,11,12} ....})

so i can run a foreach() over the arr

How would i do that?

--

Thanks in advance and for help and time.

Hi,

VEX doesn't have arrays of arrays (jagged arrays) but you can emulate them using 2 arrays: one flat array for the elements, another one for the start of each array for example.

Ok thanks animatrix, always helpful!

What made me go down that path was also this helpdocument which uses what i need.

The first code example has this



Isn´t that sort of what i need, an array stuffed with more arrays?

av = array( {1,0,0}, vector(nrandom()), t, texclr, {.5,0,0});

Thats only an array of vectors. Array of arrays doesn't even work if you try to hide them with a struct, i.e. an array of structs. SESI is aware of this limitation.

I guess a dictionary attribute could work for storing multiple arrays?

Yes that would be a workaround but it's horribly inefficient in performance compared to using 2 arrays the way I described.

Oh Yes the dictionary works!
As for the performance mentioned by @animatrix_, my setups arent that performative anyway...
