For example,rng(0,"twister")sets the seed to 0 and the generator algorithm to Mersenne Twister. To avoid repetition of random number arrays when MATLAB restarts, seeWhy Do Random Numbers Repeat After Startup? For more information about controlling the random number generator's state to repeat ...
Create a matrix of random numbers with the same size as an existing array. Use the stable distribution with shape parameters 2 and 0, scale parameter 1, and location parameter 0. A = [3 2; -2 1]; sz = size(A); R = random('Stable',2,0,1,0,sz) ...
X = randn(___,typename)returns an array of random numbers of data typetypename. Thetypenameinput can be either"single"or"double". You can use any of the input arguments in the previous syntaxes. example X = randn(___,"like",p)returns an array of random numbers likep; that is, of...
This example shows how to create an array of random floating-point numbers that are drawn from a uniform distribution in the open interval (50, 100). By default,randreturns normalized values (between 0 and 1) that are drawn from a uniform distribution. To change the range of the distributio...

R = exprnd(MU) returns an array of random numbers chosen from the exponential distribution withmean parameter MU. The size of R is the size of MU. R = exprnd(MU,M,N,...) or R = exprnd(MU,[M,N,...]) returns an M-by-N-by-... array. ...
return an M-by-N-by-... array of random numbers for a two- or three-parameter distribution. NAME can be: 'beta' or 'Beta', 'bino' or 'Binomial', 'chi2' or 'Chisquare', 'exp' or 'Exponential', 'ev' or 'Extreme Value', ...
r = binornd(n,p,sz1,...,szN) generates an array of random numbers from the binomial distribution with the scalar parameters n and p, where sz1,...,szN indicates the size of each dimension. example r = binornd(n,p,sz) generates an array of random numbers from the binomial distributio...

R = NORMRND(MU,SIGMA) returns an array of random numbers chosen from a normal distribution with mean MU and standard deviation SIGMA. The size of R is the common size of MU and SIGMA if both are arrays. If either parameter is a scalar, the size of R is the size of the other pa...
