Aside from the modules and the compact solutions,
I'll try a non-obfuscated solution first ;-) This will
work on any 'text-matrix' as far as it's rectangular ...
my $inp='
1 2 3
4 5 6
a b c
x y z
';
my @data;
my @elem = grep length, split /\s+/, $inp;
my $rows = () = $inp =~/(?<=^)\w/msg;
my $cols = @elem / $rows;
for my $col (0..$cols-1) {
push @data, [ map $elem[$col + $cols*$_], 0..$rows-1 ]
}
# print the matrix
print "@$_\n" for @data;
Regards
