This module introduces students to computational modelling techniques with particular emphasis on ordinary differential equations (ODEs, deterministic and stochastic), which are essential to modelling chemical reaction kinetics, and reaction diffusion equations (partial differential equations, PDEs), important for analysing the mobility of chemical species for example. Students will gain a basic understanding of the mathematics of ODEs and PDEs, how to solve elementary problems analytically, and how to solve them numerically on the computer using Matlab.
