how can we calculate false positive and false negative for signal ? can any one provide me matlab code ?

if signal recovered its false negative and if signal is not recovered its false positive what i know that

 for ii=1:length(X_p)
 if X-p(ii)&&~any(X_rp)

i know this if any one know about that please share their idea and guidelines with me

Totally unclear. If you want an answer and cannot be any more clear than this, then give an example.
