Hello all,
I have been trying to find a package/addon that will provide a sparse array class to NumPy, or will at least trick NumPy to use a sparse array as a regular array, to no avail.
Sparse arrays are not a common object. Sparse matrices have many, many implementations of which I'm sure you're aware. What you want is a general purpose N-D array that uses some kind of sparse storage. I'm not aware of such an object in any other language. Most of the time people remap their particular problem so that any sparse arrays become sparse matrices. All of the effort is then focused in manipulating certain classes of sparse matrices. -Travis
