Converting COO objects to other Formats

COO arrays can be converted to numpy.ndarray objects, or to some scipy.sparse.spmatrix subclasses via the following methods:

• COO.todense: Converts to a numpy.ndarray unconditionally.

• COO.maybe_densify: Converts to a numpy.ndarray based on

  certain constraints.

• COO.to_scipy_sparse: Converts to a scipy.sparse.coo_matrix if

  the array is two dimensional.

• COO.tocsr: Converts to a scipy.sparse.csr_matrix if

  the array is two dimensional.

• COO.tocsc: Converts to a scipy.sparse.csc_matrix if

  the array is two dimensional.
