Supported functions from ``scipy.sparse``
=========================================

Sparse matrix support is currently experimental and limited to boxing and
unboxing of the :py:class:`scipy.sparse.csr_matrix` and
:py:class:`scipy.sparse.csc_matrix` types and support for the
:py:func:`numpy.shape` function, the property :py:attr:`ndim`, and the :py:meth:`copy`
method.
