GF2 sparse arrays supported?

[amirebrahimi]

From what I can tell sparse arrays are not supported. Is that correct?

SciPy isn't currently tested against. This morning I tried instantiating a scipy.sparse matrix and getting the finite field ufuncs to trigger and could not.

For instance, I found these methods __add__(), _add_dense(), and _add_spare() in scipy.sparse.bsr_array. However, I wasn't able to get any to use the custom finite field ufuncs constructed by FieldArray -- addition is available as FieldArray._add.ufunc, for example.

I would be happy to support them, but I haven't found the best integration with NumPy ufuncs / Numba. The principle mechanism that galois overrides of ndarray in FieldArray is __array_ufunc__(), which handles the ufunc dispatching. I haven't found such a hook in scipy.sparse matrices.

Okay. Well, thank you for looking into it and also for creating galois!
