def preserve_random_state(func):
""" Decorator to preserve the numpy.random state during a function.
Parameters
----------
func : function
function around which to preserve the random state.
Returns
-------
wrapper : function
Function which wraps the input function by saving the state before
calling the function and restoring the function afterward.
Examples
--------
Decorate functions like this::
@preserve_random_state
def do_random_stuff(x, y):
return x + y * numpy.random.random()
Notes
-----
If numpy.random is not importable, the state is not saved or restored.
