Detailed Description

Weibull distribution.

Synopsis

The <tt>Weibull</tt> class implements a weibull distribution with
parameters <tt>alpha</tt> and <tt>beta</tt>.  The first parameter to the
class constructor is <tt>alpha</tt>, and the second parameter is
<tt>beta</tt>.  It is assumed that the alpha parameter is not zero and an
AipsError exception is thrown if this is not true.  The remaining members
allow you to read and set the parameters.

<h3>Example</h3> @anchor Random_example

Thrown Exceptions

AipsError: if bad values for the arguments are given, as specified above.

To Do

Nothing I hope!

Constructor & Destructor Documentation

casa::Weibull::Weibull	(	RNG *	gen,
		Double	alpha = `1.0`,
		Double	beta = `1.0`
	)

Construct a random number generator for a uniform distribution.

The first argument is a class that produces random bits. This pointer is NOT taken over by this class and the user is responsible for deleting it. The remaining arguments define the parameters for this distribution as described in the synopsis.

virtual casa::Weibull::~Weibull ( ) [virtual]

The destructor is trivial.
