You can certainly call it a matrix if you want to, but other people may not
know what you mean. (I didn't, when I read your original post.) The
standard Perl terminology is to call it an array of arrays.
foreach and for in Perl are completely interchangeable.
These two are the same:
foreach my $x (@list)
for my $x (@list)
These two are also the same:
for (my $i = 0; $i < 10; ++$i) {
foreach (my $i = 0; $i < 10; ++$i) {
Which you use is merely style/personal preference.
