sodes

sodes()

Returns symbolic ODE right-hand side expressions for all species. The rate of change of a specie concentration is given by

\[ \frac{dn}{dt} = \sum_{i} (-1)^a f_i\begin{cases} & a = 0 \text{ when } n \text{ is a product} \\ & a = 1 \text{ when } n \text{ is a reaction} \end{cases} \]
