Section: Random Number Generation
Generates a vector of exponential random variables with the specified parameter. The general syntax for its use is
y = randexp(lambda)
where lambda is a vector containing the parameters for the generated random variables.
The exponential random variable is usually associated with the waiting time between events in a Poisson random process. The PDF of an exponential random variable is:
Here is an example of using the randexp function to generate some exponentially distributed random variables
--> randexp(ones(1,6))
ans =
