Zeros Vector Breaks Execution

[Sinansi]

Hello,

I am running an application that loops over InformationMeasures.get_mutual_information.
If you pass a vector with all elements containing zero (example, Base.zeros()) to this function, the execution of the loop breaks and an error is displayed on the screen.

I suggest if a zeros vector is passed to this function, it just returns a mutual information of 0.0 instead of interrupting the execution of the loop/application.

Thank you!

This actually happens whenever a vector contains equal elements: could be zeros, ones, or tens, for example.
For a vector named vec, you can check if all elements are equal by using the following function:
allequal(vec) = all(y->y==vec[1],vec)
