# You need to pass a reference!
my $arg = SomeFunction(\my @arry =qw/one two three/);
sub SomeFunction {
my $array = shift;
# Iterate over rows
foreach my $row (@{$array}) {
# Iterate over columns
foreach my $element (@{$row}) {
print "$element ";
}
# Newline to start next row
print "\n";
}
}
perldoc perlref # Read up on references
