gamrnd (Statistics Toolbox)

Random numbers from the gamma distribution

Syntax

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

Description

R = gamrnd(A,B) generates gamma random numbers with parameters 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 = gamrnd(A,B,m) generates gamma random numbers with parameters A and B, where m is a 1-by-2 vector that contains the row and column dimensions of R.

R = gamrnd(A,B,m,n) generates gamma random numbers with parameters A and B, where scalars m and n are the row and column dimensions of R.

Examples

n1 = gamrnd(1:5,6:10)
n1 =
    9.1132   12.8431   24.8025   38.5960  106.4164
n2 = gamrnd(5,10,[1 5])
n2 =
   30.9486   33.5667   33.6837   55.2014   46.8265
n3 = gamrnd(2:6,3,1,5)
n3 =
   12.8715   11.3068    3.0982   15.6012   21.6739
