Random number stream - MATLAB - MathWorks

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. 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 …
