I am trying to read a csv file into a 2D array matrix

I am having a hard time trying to get the array returned by split
function to "attach" to a 2D array.

See the code below for further info on what I'm trying to do ....

## initialize
$row = 0;
$col = 0;

## go thru each line of file
while (<STDIN>) {

  ## need to correct below line to append array returned by split to
$matrix[$row][ ....]
  $matrix[$row] = split (/,/, $_);

   ##
   ## more code
   ##

   $row = $row + 1;
}

## need the above so i can do something like below
print $matrix[1][1];

Is there a way to do this?

Yes, you need to create an anonymous array to hold it.

 $matrix[$row] = [ split (/,/, $_) ];
