I need to write a function that generates two numbers that are between the negative and positive values of an integer. For example, if I call the function and input 7 it should generate two random numbers between -7 and +7. Every time you initialize the generator using the same seed, you always get the same result. Stack Exchange Network. Restore State of Random Number Generator to Reproduce Output. Based on your location, we recommend that you select: . The State property is the internal state of the random number generator. In the original matlab function, I used the in-built randn() function to generate the random numbers. In matlab, one can generate a random number chosen uniformly between 0 and 1 by x = rand(1) the rand command gives float numbers between 0 and 1. The simplest randi syntax returns double-precision integer values between 1 and a specified value, imax. In order to generate a random sequence of events, we will utilize MATLAB’s rand function, which we have previously discussed. rng: This controls the random number generation; RandStream: This is used for the stream of random numbers. https://nl.mathworks.com/matlabcentral/answers/86209-how-can-i-generate-a-single-random-number#answer_95679, https://nl.mathworks.com/matlabcentral/answers/86209-how-can-i-generate-a-single-random-number#comment_816250, https://nl.mathworks.com/matlabcentral/answers/86209-how-can-i-generate-a-single-random-number#comment_816390.
