Discrete (multinomial) distribution sampler

Random number generator of a discrete (multinomial) distribution

Description

Generate samples from a discrete distribution or multinomial distribution specified by discrete probability parameters.

usage:
x = discreternd(p,n);

p is a vector of the discrete probabilites (sum(p)==1)
n is the desired number of samples.

if length(p)==d, then x is a vector of n integers in [1,d].

example

>> discreternd([.2,.3,.5],10)

ans =

     1 3 3 2 3 1 2 3 3 3

Forgive my poor English, but what does it suppose to mean?

[Tim Benham]

It means someone has already posted a function that uses the same method.
