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

.. py:function:: B_matrix(Nc: int, col_subs: numpy.ndarray, col_prod: numpy.ndarray) -> numpy.ndarray

   Build the B matrix for the :math:`\eta^{kin}` expression.

   row_subs : np.ndarray
       A column from the substrate stoichiometric matrix. We assume
       coefficients represent reactant molecularities so
       only integer values are allowed.

   row_prod : np.ndarray
       A column from the product stoichiometric matrix. We assume
       coefficients represent reactant molecularities so
       only integer values are allowed.


.. py:function:: logistic(x: numpy.ndarray) -> numpy.ndarray

   elementwise calculation of :math:`\log(1 + e^x)`
