i was of the impression that to get an analytic signal
from real signal Y = yr(real signal) + j*hilbert(yr);
is it right???

Despites its silly name ( http://www.mathworks.com/matlabcentral/answers/3134-hilbert-transform ), the hilbert function return the analytic signal
load handel
yr = hilbert(y);

Depends what you mean by hilbert(yr) ... If you mean the Hilbert transform, then yes. If you mean the oddly named function in MATLAB, then no. The hilbert function in MATLAB does not return the Hilbert transform, rather it returns the analytic signal. The link I provided takes you to a similar question that I asked a while back.
