If the samerandom seed is deliberately shared, it becomes a secret key, so two or more systems using matching pseudorandom number algorithms and matching seeds can generate matching sequences of non-repeating numbers which can be used to synchronize remote systems, such as ...
Generate correlated Gaussian sequences by Fourier synthesis. Input parameters: rgau = correlation function - length n/2 m = number of realisations Output: cg = m x n matrix containing m sequences of n correlated variates from a zero mean, unit variance normal distribution psg = input power...
