betarnd (Statistics Toolbox)

Random numbers from the beta distribution.

Syntax

R = betarnd(A,B)
R = betarnd(A,B,m)
R = betarnd(A,B,m,n)

Description

R = betarnd(A,B) generates random numbers from the beta distribution with parameters specified by A and B. Vector or matrix inputs for A and B must have the same size, which is also the size of R. A scalar input for A or B is expanded to a constant matrix with the same dimensions as the other input.

R = betarnd(A,B,m) generates a matrix of size m containing random numbers from the beta distribution with parameters A and B, where m is a 1-by-2 vector containing the row and column dimensions of R.

R = betarnd(A,B,m,n) generates an m-by-n matrix containing random numbers from the beta distribution with parameters A and B.

Examples

a = [1 1;2 2];
b = [1 2;1 2];
r = betarnd(a,b)
r =
    0.6987    0.6139
    0.9102    0.8067
r = betarnd(10,10,[1 5])
r =
    0.5974    0.4777    0.5538    0.5465    0.6327
r = betarnd(4,2,2,3)
r =
    0.3943    0.6101    0.5768
    0.5990    0.2760    0.5474
