Normally distributed random numbers - MATLAB randn

Tīmeklis2012. gada 27. okt. · Matlab randn generates realisations from a normal distribution with zero mean and a standard deviation of 1. Samples from any other normal distribution can simply be generated via: numSamples = 1000; mu = 2; sigma = 4; samples = mu + sigma.*randn (numSamples, 1); You can verify this by plotting the … TīmeklisI tried to implement the DL algorithm presented in the paper, Poojan Oza, and Vishal M.
