Generate repeatable random noise using the rng function before calling the awgn function. Get rng(seed); y = awgn(x,snr); Compute the bit errors. Get dataHat = pskdemod(y,M); numErr1 = biterr(data,dataHat,k) numErr1 = 309 Reset the random number generator seed. Get rng(see...
Set the seed and type of the random number generator for reproducibility of the results. Get rng(0,'twister'); % For reproducibility Generate sample data with 300 observations and 3000 predictors, where the response variable depends on the 4th, 7th, and 13th predictors. Get N = 300; ...
