WebbThe terms 'seed' and 'state' are misleading names for the generators. 'seed' refers to the MATLAB v4 generator, not the seed initialization value. 'state' refers to the v5 generators, … WebbThe RAND function uses the Mersenne-Twister random number generator (RNG) that was developed by Matsumoto and Nishimura (1998). The random number generator has a very long period (2 19937 – 1) and very good statistical properties. The period is a Mersenne prime, which contributes to the naming of the RNG.

Webbrand ("seed", val) which sets the seed of the generator to val. The seed of the generator can be queried with s = rand ("seed") However, it should be noted that querying the seed will not cause rand to use the old generators, only setting the seed will.

WebbThe output of RAND, when called with one string input argument, is the internal state of the generator specified by the string argument (the form of the internal state is described in the documentation of RAND). If init is a scalar double precision number, i.e. a seed, this number is used to create the internal state. Webbrand_cache_size = integer() Sets the cache size in bytes to use by crypto:rand_seed_alg(crypto_cache) and crypto:rand_seed_alg_s(crypto_cache) . This parameter is read when a seed function is called, and then kept in generators state object.
