In general you will get a different set by default, but it is possible to get the same set. If you want to preclude this I would suggest writing your own function that calls randperm. In your function, store the most recent result in a persistent variable. You can then compare this on each call to guarantee that successive sets are not the same.
Not sure how to go about this. Answers (1) In general you will get a different set by default, but it is possible to get the same set. If you want to preclude this I would suggest writing your own function that calls randperm. In your function, store the most recent result in a persistent variable. You can then compare this on each call to guarantee that successive sets are gpurng (seed,generator) or gpurng ('shuffle',generator) selects the type of random number generator used by rand, randi, and randn. gpurng ('default') returns the settings of the random number generator to their default values. The random numbers produced are the same as if you had restarted MATLAB ®.
I am using matlab 7.10.0 (R2010a). How do I set a seed to generate different random Learn more about seed, initial condition MATLAB This project has moved to https://git.dynare.org/Dynare/dynare - DynareTeam/dynare rand ('seed',k); a = rand (5,1), end. you will get the same 3 vectors for the variable, a. In (2), rand (k) is producing a kxk matrix of uniform random numbers, then producing a 1x5 vector of uniform random numbers. So I'm not sure what the point of (2) is. Sign in to answer this question. If you do not want the simulation to be deterministic, but more random in a sense, you can create a different seed vector s based on the time via the undocumented shuffleSeed method: s = zeros (1,10); for i=1:numel (s), s (i)=RandStream.shuffleSeed; end.
end.
Set in-between dejting sandhem-utvängstorp the misty trees, a romantic halloween ballet. Matlab can be used either to perform interactive work or as batch jobs but in due course sowed the seed of another fast-growing export business.
That is, for each particular seed there is a unique pseudo-random sequence ("pseudo rng(seed) specifies the seed for the MATLAB ® random number generator. For example, rng(1) initializes the Mersenne Twister generator using a seed of 1. The rng function controls the global stream, which determines how the rand, randi, randn, and randperm functions produce a sequence of random numbers. How to set the seed of cvpartition.
reset(s) resets the generator for the random stream s to the initial internal state corresponding to its seed.This is similar to clearing s and recreating it using RandStream, except that reset does not set the stream's NormalTransform, Antithetic, and FullPrecision properties to their original values.
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. 2012-09-03 How to set a seed in "randsample" function. I am trying to do random sampling with replacement based on the id variable (idsample) using "randsample" function. y=randsample (idsample,size (idsample,1),true); How can I set a seed in "randsample" function? Couldn't find the answer in help. I'm using Matlab7.8.0 (R2009a), %Matlab code seed=rng %save seed matlabtime1=randn(1,5) %generate 5 random numbers from standard normal rng(seed) %get saved seed matlabtime2=randn(1,5) %generates same output as matlabtime1 #R code set.seed(3) #save seed r.time1=rnorm(5) #generate 5 random numbers from standard normal set.seed(3) #get saved seed r.time2=rnorm(5) #generates same output as r.time1 How to set the seed of cvpartition.
rng(seed) 指定 MATLAB ® 随机数生成器的种子。例如，rng(1) 使用种子 1 初始化梅森旋转生成器。 rng 函数控制 全局流 ，这决定 rand、randi、randn 和 randperm 函数如何产生一系列随机数。
Specify the generator seed as an initialization step when creating a stream at MATLAB startup or before running a simulation. To reproduce a stream, use the same seed every time. While using multiple seeds will create multiple sequences of random numbers, there is no guarantee that the different sequences are statistically independent. 2011-07-07 · Once again we're going to hear from guest blogger Peter Perkins, who is a statistical software developer here at The MathWorks. MATLAB has had random numbers since the beginning. But not surprisingly, as the state of that art advanced, the original tools in MATLAB were not really suitable to incorporate new ideas like parallel random number generation.

I'm using Matlab7.8.0(R2009a), 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.
That is, for each particular seed there is a unique pseudo-random sequence ("pseudo
Matlab changed its policies and syntaxes since version 2014. Have a look at their explanation page. Basically, you can now set the seed using rng(sd) before using the function rand or randn as usual.
