How to create 2D arrays from subarrays in rows

[jmor]

If I create a 2D array with:

Local $b[2][3] = [[1, 2, 3], [4, 5, 6]]

No problem

But it would simplify my work a lot if I could create a 2D array by specifying row subarrays:

Local $a0[3] = [1, 2, 3]
Local $a1[3] = [4, 5, 6]
Local $b[2][3] = [$a0, $a1]

Apparently, this doesn't work, I get the following error:

: ==> Missing subscript dimensions in "Dim" statement.:
Local $b[2][3] = [$a0, $a1]
Local $b[2][3] = [^ ERROR

Basically, I would like to use subarrays (arrays for the rows) to construct the 2D array, and then, be able to normally retrieve the individual elements with, for example:

consoleWrite('$b01: ' & $b[0][1]

I am sure there is a work around, or there is something I overlooked.

Thanks for the help.

Just use a variable to capture the sub array for example:

Local $a0[3] = [1, 2, 3]
Local $a1[3] = [4, 5, 6]
Local $b[2] = [$a0, $a1]

;~ Get Array Items
Local $ba = $b[0]
ConsoleWrite($ba[0] & @CRLF & $ba[1] & @CRLF & $ba[2] & @CRLF & @CRLF)
$ba = $b[1]
ConsoleWrite($ba[0] & @CRLF & $ba[1] & @CRLF & $ba[2] & @CRLF & @CRLF)

;~ Or using a loop

Local $ab
For $i = 0 To UBound($b) - 1
    $ab = $b[$i]
    For $j = 0 To UBound($ab) - 1
        ConsoleWrite($ab[$j] & @CRLF)
    Next
    ConsoleWrite (@CRLF)
Next

Posted incorrect code.

*as long as they have the same number of rows,

you can also flip those sideways and slap them together

#include<array.au3>

Local $a0[3] = [1, 2, 3]
Local $a1[3] = [4, 5, 6]

_ArrayTranspose($a0)
_ArrayTranspose($a1)
_ArrayConcatenate($a0 , $a1)

_ArrayDisplay($a0)

Perfect!  I wasted too much time on this.  Both of you are bright.  Many thanks for the quick solutions.
