My point was that the current situation (i.e., people reinventing the wheel)
was a by-product of the fact that there's nothing as standardized as
numpy's ndarray or Python's buffer interface
Hi all,
I've been working quite a lot with sparse vectors and sparse matrices
(basically
as feature vectors in the context of machine learning), and have noticed
that they
do crop up in a lot of places (e.g. the CVXOPT library, in scikits, ...) and
that people
tend to either reinvent the wheel (i.
