And that would be a bad assumption. While I don't use sparse matrices, I do
use some of those functions, particularly hypot, arctan2, maximum, and
minimum (why is ones_like() a ufunc?). If I had sparse matrices, I suspect
I certainly would be using these functions just like I do for regular numpy
arrays.
