Re: [Matplotlib-users] Entropy calculation incorrect?
Eric, Thanks. I have submitted a pull request to fix the documentation as you suggested. https://github.com/matplotlib/matplotlib/pull/3018 Thanks for your help, Nathan (aka captainwhippet) From: Eric Firing efir...@hawaii.edu To: matplotlib-users@lists.sourceforge.net Sent: Friday, 25 April 2014, 19:38 Subject: Re: [Matplotlib-users] Entropy calculation incorrect? Nathan, Thanks for bringing this up. It looks like the short-term fix is to make the documentation match the code. Longer term, it seems to me like this is the sort of thing that should be deprecated; it doesn't belong in matplotlib any more. Would you open an issue on Github, please? Even better: submit a pull request that fixes the documentation.

Re: [Matplotlib-users] Entropy calculation incorrect?
This is a side-remark. Please, don't exaggerate with the term incorrect. Binary, decimal, natural... logarithms, all this is just a matter of multiplicative CONSTANT, and sometimes a question of convention. I am a physicist, and for us the entropy is NOT given in bits. We use natural logarithms, and in order to have the units appropriate for statistical physics / thermodynamics, we multiply the result by the Boltzmann constant, 1.38*10^(-23) Joule/Kelvin, and that's it. Anyway, Eric Firing is right, all this has nothing to do with Matplotlib. Best regards.

Re: [Matplotlib-users] Entropy calculation incorrect?
Jerzy, Yes, understood. The issue here is that the function is documented incorrectly and I have made a pull request to fix that. Best regards, Nathan.

[Matplotlib-users] Entropy calculation incorrect?
Hello, I have been using the matplotlib.mlab.entropy function and have noticed that it may be incorrect. I have posted a question on stackoverflow here: http://stackoverflow.com/questions/23291576/matplotlib-mlab-entropy-calculation-incorrect I thought I would should it on the mailing list too. Does anyone have any ideas?
