  Is x of dok_array type?

  Parameters:
    x

      object to check for being a dok matrix

  Returns:
    bool

      True if x is a dok matrix, False otherwise

      >>> from scipy.sparse import dok_array, dok_matrix, coo_matrix, isspmatrix_dok
      >>> isspmatrix_dok(dok_matrix([[5]]))
      True
      >>> isspmatrix_dok(dok_array([[5]]))
      False
      >>> isspmatrix_dok(coo_matrix([[5]]))
      False
