Well, that would be: 
    $a [$J * ($i - 1) + $j]

[download]
as opposed to 
    $a [($J + 1) * $i + $j]

[download]
where $J is the highest second dimensional index. (Which if indices start with 1 happens to be identical to the number of indices).

If indices start at 1, taking a slice till the end of an array can be written as: 

    $a [5 .. @a]

[download]
instead of having to write 
    $a [5 .. @a - 1]

[download]
or to have to use the $#array form: 
    $a [5 .. $#a]
