Normal random numbers


R = normrnd(mu,sigma)
R = normrnd(mu,sigma,m,n,...)
R = normrnd(mu,sigma,[m,n,...])


R = normrnd(mu,sigma) generates random numbers from the normal distribution with mean parameter mu and standard deviation parameter sigma. mu and sigma can be vectors, matrices, or multidimensional arrays that have the same size, which is also the size of R. A scalar input for mu or sigma is expanded to a constant array with the same dimensions as the other input.

R = normrnd(mu,sigma,m,n,...) or R = normrnd(mu,sigma,[m,n,...]) generates an m-by-n-by-... array. The mu, sigma parameters can each be scalars or arrays of the same size as R.


n1 = normrnd(1:6,1./(1:6))
n1 =
  2.1650  2.3134  3.0250  4.0879  4.8607  6.2827

n2 = normrnd(0,1,[1 5])
n2 =
  0.0591  1.7971  0.2641  0.8717  -1.4462

n3 = normrnd([1 2 3;4 5 6],0.1,2,3)
n3 =
  0.9299  1.9361  2.9640
  4.1246  5.0577  5.9864
