this is my code:
nSamp = 3251;
Fs = 1024e3;
SNR = 40;
rng default

t = (0:nSamp-1)’/Fs;

x = sin(2*pi*t*100.123e3);
x = x + randn(size(x))*std(x)/db2mag(SNR);

[Pxx,f] = periodogram(x,kaiser(nSamp,38),[],Fs);
meanfreq(Pxx,f);
i change the variable in this code to my dataset . then after run, the variable go to its original data . how to solve this problem?this is my code:
