printing elements of an arrays of references

[Pedro Soto]

Dear all,
I am trying to make a matrix out of a file (row-columns) using perl. In
particular I would like to print the first row of an array of arrays which
contains the headings of the file.
I tried to do it but I can't print it. If used $AoA[0], I get the reference
to the array.How can I deference it?
Thanks in advance,
P


#! usr/local/bin/perl
use warnings;
use strict;
my @AoA= ();
open(IN,"genotypes_piece") || die "I can not open file\n";
my @temp =();
while (defined (my $line = <IN>)) {
@temp = split/\s+/,$line;
push(@AoA, [EMAIL PROTECTED]);

}
for (my $x = 11; $x <=$#temp; $x++) {
     for (my $y = 1; $y <= $#AoA ; $y ++) {
     print "At X=$x, Y=$y is", $AoA[$y][$x], "\n";
}
}
