Understanding multidimesional arrays

22 posts in this topic

I search this a few times using varying forms of "multidimesional arrays" and nothing turned up, so I'm gonna go ahead an ask. Can someone help me understand multidimesional arrays and show me how to set one up? A HIGHLY commented example script would also work. Thanks.

#include <Array.au3>

Local $1DArray[3] = ["el-0/col1", "el-1/col1", "el-2/col1"]; manually create a one dimensioanal array with 3 elements
_ArrayDisplay($1DArray, "1D Array") ;Show it
Local $2DArray[3][2] ; this is declaring a 2D array, with 3 elements and 2 colums

For $i = 0 To 2
    $2DArray[$i][0] = $1DArray[$i] ;add the same elements fron first 1D array to colum 0 of our 2D array
    $2DArray[$i][1] = "el-" & $i & "/col1";; add values for the  second colum (colum 1)
Next

_ArrayDisplay($2DArray, "2D Array")

So basically it's like a standard array but each element has more details added by another dimension? Also, how would I manually set up a multidimensional array compared to $array[3] = ["1", "2", "3"]?

Something like this >>

Okay, Thanks! :mellow: I'll probably use multidimensional arrays sometime in the future. IDK when though.

Yeah and the 4-dimensional array is a bit confusing and intimidating to me, as it is huge, but I'm highly sure I understand Multidimensional arrays now. Thanks for all the help guys.

@Guiness what's :mellow: for? I don't know why you posted it... and I don't know how to respond to it... :)

To me an 4D array is like two tables.. where every element of the first table point to another table

Its not really a 4D array its just 2 dimensional Rows and colums, just more of them.

A 3D array would be something like

$3DArray[3][3][3], but I'm unsure if autoit3 supports that sort of madness, I'd visualize that as a rubiks cube type thing.

Never say never, but for most a two-dimensional array is suffice for most applications.

I like to get out the hookah and put on Ravi Shankar records when I consider anything "multi-dimensional".

Seriously, like they said, it's still just a basic flat array with some fancy referencing tacked on allowing you to group, or logically organize and retrieve the data.

A simple array like:

$aNames[8] = ["Bob", "Carol", "Ted", "Alice", "Fido", "Fifi", "Mickey", "Minnie"]

is still the exact same 8 fields of data whether it's defined as $aNames[4][2] or $aNames[2][4] or $aNames[2][2][2].

But had I a need to organize humans and non-humans seperately, then I might define the array like this:

$aNames[2][4] = [["Bob", "Carol", "Ted", "Alice"],["Fido", "Fifi", "Mickey", "Minnie"]]

Elements [0][0-3] would be the humans, and elements [1][0-3] the critters.

Or if I wanted to keep the "couples" together, then:

$aNames[4][2] = [["Bob", "Carol"],["Ted", "Alice"],["Fido", "Fifi"],["Mickey", "Minnie"]]

I guess you could think of a multidimensional array as an array within an array. Each array element contains an array.

He, bah.

Liked this one better.

JohnOne,

a banana is a herb

[Off Topic][Pedant Mode]

The yellow thing you peel and eat is most definitely a fruit - although as commercially grown banana plants are sterile, the "seeds" are merely the little black specks within the flesh.

It is the banana plant on which the fruits grow which is technically a herb as the stem does not contain true woody tissue.
