I'd estimate the effort it would take to convert scipy.sparse to ndarray semantics is about a couple of afternoon hacks (normal, not Ipython-size), so it should be doable. Also, a shorthand for right-multiplication is probably necessary, as A.T.dot(B.T).T is unwieldy. As far as backward compatibility goes: change from * to .dot would break everyone's code. I suspect the rest of the changes have smaller impacts. The code breakage is such that I don't think it can be easily done by changing the behavior of "csr_matrix". I've previously proposed adding csr_array et al., and deprecating csr_matrix et al.. Not sure if the *_matrix can ever be removed, but it would be useful to point new users to use the interface with the ndarray convention. -- Pauli Virtanen _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
