Elizabeth Million was a student in a course of mine a few years ago and this was her final project paper. I asked her to polish it up and she contributed it as Section HP of my textbook (which I see now has a consistent problem with the subscripts on the Hadamard identity): http://linear.ups.edu/jsmath/latest/fcla-jsmath-latestli101.html Exercise T30 talks about connections with the singular value decomposition, and her original paper contains some more involved theorems and results that she didn't work up for the section of the book. So the operation is not without interest, I believe. Working with Elizabeth, it was obvious to me that this was consistently called the Hadamard Product by those who studied it. However, I would agree that "elementwise_product()" would be much more obvious to one browsing the available functions. So having "hadamard_product()" as a synonym, or at least prominently included in the documentation would be desirable. Given the apparent ease of implementing this, I'd consider it a useful addition.
