Tools
We used the following tools for modelling and simulation:
- MATLAB version 8.3.0.532 (R2014a). Natick, Massachusetts: The MathWorks Inc., 2014. for deterministic model, curve fitting and parameter estimation.
- COMSOL Multiphysics software Version 4.4.0.248, COMSOL Ltd, 2014, for diffusion model and simulation.
- MEIGO Toolbox for parameter estimation.[26]
