이를 위해서는 이전의 프로그램 언어들과 유사하게 MATLAB에서도 random number 생성에 관여하는 random seed를 고정함으로써 생성되는 값을 조정할 수 있다. This is similar to clearing s and recreating it using RandStream , except that reset does not set the stream's NormalTransform , Antithetic , and FullPrecision I have been able to solve the problem with a custom Random Number generator, but I think, that you should consider changing this in future generations of Matlab. Hi,. I am using the following code in a simulation. I need to use a seed to generate the same random numbers. can Use the rand , randn , and randi functions to create sequences of pseudorandom numbers, and the randperm function to create a vector of randomly permuted Learn more about seed, random number. The seed is not changing when I close the Matlab and open a new one. The seed is always being set as 0.

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).

rng(54321); You can also reseed it "unpredictably" using. rng shuffle This example shows how to repeat arrays of random numbers by specifying the seed first.
There is a block named 'Random Integer Number' or something like this that can produce different seed for your iterations even when fast restart is on. You can place this block in a simulink function and use it in entity generator as seed.

If you are feeling lucky, try playing around with the settings. For example try using the (outdated) seed input to matlabs random functions. 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. 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. 2011-07-07 · For example, to reinitialize MATLAB's random number generator to its default settings, you use this command. rng default.

I am using random ('Normal',2,5,T,1) to generate vector of random numbers from normal distribution with mean 2, variance 5. 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). You can just call rng (mySeed) to set the seed for the global stream (tested in Matlab R2011b). This affects the rand, randn, and randi functions. The same page that James linked to lists this as the recommended alternative to various old methods (see the middle cell of the right column of the table). Here's some example code: One simple way to avoid repeating the same random numbers in a new MATLAB session is to choose a different seed for the random number generator.
