Paulo has reached a reputation level sufficient to have been invited to be a MATLAB Answers Community Editor; I do not, though, know whether the configuration change needed for him to actually edit has gone through yet.
The Community Editors have access to the normal "edit" button on all Answers, and can delete any Comment or Answer or even Question; the buttons for doing that are simply the normal buttons that the original poster would have.

Walter and Sean my editor status is still waiting to be implemented but I really don't have time do be here editing messages (have just a month to finish my thesis), my main reason to be here is just to learn and try to help others.

b_p = ones(size(b));
b_p(~b) = -1;
bw = [kron(b_p,ones(1,100)) b_p(end)];
creates the same thing you have for b_p, bw...
