<H2>RANDEXP Generate Exponential Random Variable
</H2>
<P>
Section: <A HREF=sec_random.html> Random Number Generation </A>
<H3>Usage</H3>
Generates a vector of exponential random variables with
the specified parameter. The general syntax for its use is
<PRE>
y = randexp(lambda)
</PRE>
<P>
where <code>lambda</code> is a vector containing the parameters for
the generated random variables.
<H3>Function Internals</H3>
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:

<H3>Example</H3>
Here is an example of using the <code>randexp</code> function to generate
some exponentially distributed random variables
<PRE>
--> randexp(ones(1,6))
ans =
0.0608 0.0019 1.1266 0.2012 0.5079 3.4205
