Assuming that I want to fill a 2D array(not piddle) by reading in a coma delimited text, I'd probably go about as follows:

Note that  @tempimage's each row is a coma delimited text, and it's # of rows are greater than 1. 

my @image2D=undef;
for(my $ix=0; $ix<scalar @tempimage; $ix++)
{
   my @temp=split("\,",$tempimage[$ix]);
   for(my $iy=0; $iy<scalar @temp; $iy++)
    {
    $image2D[$ix][$iy]=$temp[$iy];
    }                
}

So, for each row in  @tempimage, I can split the coma delimited values and replace them to a column in a 2D perl array(which is  @image2d), and I can access any element by saying  $image2D[$index_1][$index_2]

How can I fill a pdl in the same fashion? Can I also create a nested for loop and manipulate the contents of a pdl? Must I create a pdl of zeros and fill the zero indices?

Thanks for all the input!
