@rot_mat is an array of array references, that's why you see three fields in the output from your print statement. If you wanted to print all values of $rot_mat[0] then you would need to do

print @{$rot_mat[0]};

or just use Data::Dumper on \@rot_mat to get the full tree. See perldsc for more on these nested structures and the section "Access and Printing of an ARRAY OF ARRAYS" for this particular question.
