As mentioned in #40 scipy encourages the usage of _array over _matrix:
This package [scipy.sparse] is switching to an array interface, compatible with NumPy arrays, from the older matrix interface. We recommend that you use the array objects (bsr_array, coo_array, etc.) for all new work.

We might want to embrace this transition and ditch
