Use the rng function to control the repeatability of your results. Use the RandStream class when you need more advanced control over random number generation. How to set the same initial seed random numbers in Matlab? Tag: matlab , random I have a matlab code which has a bunch of random numbers such as: unifrnd(0,1) , normrnd(mu,sigma) , this sort of functions get repeated over and over again.

I am using matlab 7 Setting up the random number generator seed in Matlab and Octave Mike Croucher as an interesting post on correctly and incorrectly setting up the seed in Matlab. I want to set the seed so that I can get same set of random numbers each time I run the m file. I am using matlab 7.10.0 (R2010a). In that version of MATLAB, I am We start a new MATLAB, and the following lines are always true on my Mac Pro. >> rand () ans = 0.8147 >> randn () ans = 1.8339 A nice way to have true random values every run, we could suggest to initialize the random seed with current computer time. Why not call R from within Matlab and thus derive all random numbers consistently? I imagine you could write a small R script in Matlab that would set.seed in R and return your vector of generated numbers into Matlab.

It is used in many programming languages for the generation of random values within the specified range. The seed value needed to generate a random number. If it is an integer it is used directly, if not it has to be converted into an integer. Default value is None, and if None, the generator uses the current system time. Setting seed in random ('normal'). Learn more about seed, random MATLAB The objective of this tutorial is to give you a holistic understanding of generating repeatable random numbers in Matlab.
