``mx.symbol.random_exponential``
================================================================

Description
----------------------

Draw random samples from an exponential distribution.

Samples are distributed according to an exponential distribution parametrized by *lambda* (rate).


**Example**::

	 
	 exponential(lam=4, shape=(2,2)) = [[ 0.0097189 ,  0.08999364],
	 [ 0.04146638,  0.31715935]]
	 
	 
Usage
----------

.. code:: r

	mx.symbol.random_exponential(...)
