Random numbers from the Poisson distribution.
Syntax
R = poissrnd(LAMBDA) R = poissrnd(LAMBDA,m) R = poissrnd(LAMBDA,m,n)
Description
R = poissrnd(LAMBDA) generates Poisson random numbers with mean LAMBDA. The size of R is the size of LAMBDA. R = poissrnd(LAMBDA,m) generates Poisson random numbers with mean LAMBDA. m is a 1-by-2 vector that contains the row and column dimensions of R. R = poissrnd(LAMBDA,m,n) generates Poisson random numbers with mean LAMBDA. The scalars m and n are the row and column dimensions of R.Examples
Generate a random sample of 10 pseudo-observations from a Poisson distribution with
= 2:
lambda = 2;
random_sample1 = poissrnd(lambda,1,10)
random_sample1 =
1 0 1 2 1 3 4 2 0 0
random_sample2 = poissrnd(lambda,[1 10])
random_sample2 =
1 1 1 5 0 3 2 2 3 4
random_sample3 = poissrnd(lambda(ones(1,10)))
random_sample3 =
3 2 1 1 0 0 4 0 2 0
