% Can combine or negate relational expressions giving true/false using
% the usual logical Boolean operators and, not, or.  In matlab,
% 
% ----------------    ------ 
% Boolean operator    symbol 
% ----------------    ------ 
%      and              &
%      or               |
%      not              ~
% 
% Those follow the usual Boolean rules: when t = true and f = false,
% 
%     t & t = t
%     f & t = f
%     t & f = f
%     f & f = f
% 
%     t | t = t
%     f | t = t
%     t | f = t
%     f | f = f
% 
%     ~ t   = f
%     ~ f   = t

% Since true and false are represented in Matlab via 1 and 0, it can
% be confusing at times whether an integer/double or boolean is meant!
