Hi, a simple query. Do you know how could I plot the entropy function in Mathematica? I wish to produce an image similar to this one: http://upload.wikimedia.org/wikipedia/commons/c/c9/Binary_entropy_plot.png Do you know how could I plot mutual information between two random variables X and Y in a 3D surface in Mathematica? Thanks! Paul.
