reaction_twoway_ode

reaction_twoway_ode, an Octave code which sets up and solves the ordinary differential equations (ODE) which model a two-way chemical reaction between species W1 and W2.

The reference suggests an experiment in which the Forward Euler method is used, with a timestep of 1/50. The problem is to be solved three times, with the second reaction coefficient, k2, set to 10 (the default), 100, and 1000. The value k2=1000 makes the solution very difficult to compute accurately.
