## RANDP Generate Poisson Random Variable

Section: Random Number Generation

### Usage

Generates a vector Poisson random variables with the given parameters. The general syntax for its use is

       y = randp(nu),

where `nu` is an array containing the rate parameters for the generated random variables.

### Function Internals

A Poisson random variable is generally defined by taking the limit of a binomial distribution as the sample size becomes large, with the expected number of successes being fixed (so that the probability of success decreases as `1/N`). The Poisson distribution is given by

### Example

Here is an exmaple of using `randp` to generate some Poisson random variables, and also using `randbin` to do the same using `N=1000` trials to approximate the Poisson result.

    --> randp(33*ones(1,10))

    ans =

     31 33 34 44 32 29 34 30 32 32

    --> randbin(1000*ones(1,10),33/1000*ones(1,10))

    ans =

     32 36 36 39 33 34 41 33 42 32
