Dear Monks,
I have 2 arrays of arrays (let's call them @AoA_first and @AoA_second that have same amount of lines and columns. What I want to do is read through each of them, and print in a file, each column of each array of arrays, separated by tabs.
I managed to do so with the following code, but the thing is that it is very slow and there has to be a faster way that I am not aware of...
Please advise!
for $i ( 0 .. $#AoA_first ) 
{
    $row_first = $AoA_first[$i];
    $row_second = $AoA_second[$i];
    open TEMP, ">TMPFILES/$i.tmpfile";
    for $j ( 0 .. $#{$row_first} ) 
    {
        print TEMP "$row_first->[$j]\t$row_second->[$j]\n";
    }
    close TEMP;
    }
}

I think it is slow for me because it reads through every element of every column of each of the two array of arrays, but I can't think of another way to "dump" the two columns side by side into a new file...
