1) Why use $_ when you can have a perfectly fitting
descriptive variable name like $row?

2) If you're creating a copy of the row data, then
the shift is superfluous.

print "Matrix is as follows :- \n";
foreach my $row (@arr) {
  print "Row = @$row\n";
  my($key, @vals ) = @$row;
  $h{$key} = [EMAIL PROTECTED];
}

Cheers,
Thomas
