Module Contents
---------------

.. py:function:: consume_interval(low, high)

   initialise an interval matrix from `low, high` arrays;

   .. note:: initialise from the shape (2, m, n) as preferred;

   .. rubric:: Example

   low = np.arange(9).reshape(3,3)
   high = np.arange(10, 19).reshape(3,3)


.. py:function:: create_interval(matrix, half_width=0.1)

   mannually create an interval matrix from a numpy array


.. py:function:: dot(x, y)

.. py:function:: rowcol(W, x)

   marco's original implementation of the rowcol function


.. py:function:: rowcol2(x, W)

   Leslie changed the argument order for notational convecience original implementation of the rowcol function

   :param - W: have to be a vector;


.. py:function:: consume_list(list_intervals)

   consume a list of interval matrices into a single interval matrix

   ! of no use now
   .. note:: - being used for interval matrix multiplication


.. py:function:: intvl_matmul(x, W)

   draft matrix multiplication function for interval matrices

   .. note:: - can be used for general matrix multiplication

   :returns:

             - an interval matrix
