Random Number Generation. Seeds, distributions, algorithms. Use the rand, randn, and randi functions to create sequences of pseudorandom numbers, and the randperm function to create a vector of randomly permuted integers. Use the rng function to control the repeatability of your results. Use the RandStream class when you need more advanced control

The key takeaway is that one should not use rand ('seed',x) or rand ('state',x) to reset the random number seed, since Matlab defaults to an inferior generator used in older versions. It is preferable to use rng (x) instead. GNU Octave on the other hand has a less quirky take on the whole thing.

The seed specifies the starting point for the algorithm to generate random numbers. Specify the seed when you want reproducible results. The maximum value of the seed is 2 32-1. Example: tallrng(3) This MATLAB function sets the starting point, or seed, of the random number generator used in GPU calculations, so that rand, randi, and randn produce predictable sequences of numbers. Random number seed, specified as a nonnegative integer.

The simplest way to generate arrays of random numbers is to use rand, randi, randn, and randperm functions. These functions all rely on the same stream of uniformly distributed random numbers, known as the global stream.Changing the global stream can involve RandStream, but it does not have to. The objective of this tutorial is to give you a holistic understanding of generating repeatable random numbers in Matlab. Through this tutorial, I 've suppos That is, for each particular seed there is a unique pseudo-random sequence ("pseudo" means it actually repeats itself for obvious reasons of practical realizibility). It is used, therefore, as a Divide targets into three sets using random indices.

The seed you give to rng is the initiation point for the Mersenne Twister algorithm (by default) that is used to generate the pseudorandom numbers. If you choose two different seeds (no matter their relative non-negative integer values, except for maybe a special case or two), you will have effectively independent pseudorandom number streams.

The simplest random number generator is called a “linear congruential” generator. The way it works is that it starts with a seed, multiplies it by a huge number, such 

This MATLAB function returns a single uniformly distributed random number in the interval (0,1). You can generate pseudorandom numbers in MATLAB ® from one or more random number streams. The simplest way to generate arrays of random numbers is to use rand, randi, randn, and randperm functions.
