_MaxArrayIndex on n-dimensional arrays

[jimollerhead]

Not a big deal, but I have a 2-dimensional array, currently 10 x 4 (the 4 being constant for each first element) I wondered if it was possible to compute the max array element for the first subscript?

Given that I am populating the array in my code it isn't a big deal (I have just declared a constant that I alter when I add rows to the array) but it kindof "offends my programmers sensibilities" to not be able to determine the max first subscript programmatically.

UBound() is used to determine how may elements you have in your array, or elements of a particular dimension when you use the 2nd parameter of UBound().

have a look at UBound().

have a look at UBound().

UBound returns the size of an array dimension. I don't think that's what he means. He means something like this, which does not work:

; this code gives an error in Array.au3 because _arrayMax(Index) wants a single-dimensioned array.
#include <Array.au3>

Dim $testArray[3][3]

For $x=0 To 2
    For $y=0 To 2
        $testArray[$x][$y]=4*$x+8*$y
    Next
Next

MsgBox(0,"test","Biggest value in testArray - "&_ArrayMax($testArray))

I wanted to do this too some time ago, but since it did not work, I created a workaround by using a nested for-loop for both dimensions and checking myself (but those were 2 dimensions with less than 50 elements, and search speed was not a big issue so I did not bother to look for a more professional approach).

If anyone has better ideas about this then I would like to know too
