hello sir i want to find a nonzero number in my total error signal ?

my original signal is X and my Recovered signal is X_re and the total Error which i count between them is Error=X-X_re; now i have to find nonzero number in my error signal so how can i will find it thanks in advance

[John BG]

what is the context?

are you reading from and instrument?

what is the type of X X_re and Error? double?

why do you ignore X_im?

please supply a sample in same way you attempt to process, whether file or workspace variables

sir my Error is Complex double

Answer 1

[KSSV]

idx = find(Error~=0) ; % Gives the indices of non-zero numbers in Error

[irfan]

k_r1=N-number; Rate=k_r1/N Rate_3(snr_num)=mean(Rate(snr_num,:)); sir when i find number of nonzero values and run it its gives me error after some values because i want to find snr from 10 to 50 db for 100 experiments
