dS )MatrixCachea  A cache for small matrices in different formats.

    This class takes small matrices in the standard ``sympy.Matrix`` format,
    and then converts these to both ``numpy.matrix`` and
    ``scipy.sparse.csr_matrix`` matrices. These matrices are then stored for
    future recovery.
