and to reinitialize it with the seed 54321, you use this. 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. Every time you initialize the generator using the same seed, you always get the same result. Generate Random Numbers That Are Different. This example shows how to avoid repeating the same random number arrays when MATLAB restarts. I want to set the seed so that I can get same set of random numbers each time I run the m file.

For example, rng(1) initializes the Mersenne Twister generator using a seed of 1 .

2012-09-03 · Mike Croucher as an interesting post on correctly and incorrectly setting up the seed in Matlab. 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.

Matlab set random seed

rand ('seed', 1); disp (rand); 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 rng (seed) specifies the seed for the MATLAB ® random number generator.

MATLAB has several tools for generating random numbers. The most commonly used Generate a 4x4 MATRIX of random numbers, all between 0 and 1.
