The course focuses on data pre-processing, processing and visualisation for use with dissertation work. It includes introductory elements of Matlab and Simulink, currently a de facto visualisation and numerical processing standard. Some comparison to other programming languages, in particular Fortran and C, is provided. The main programming elements are introduced and used in examples: data input, processing, output in numerical and graphical forms, programming tools and structures (loops, conditional statements and other flow control). The course introduces selected principles of dynamic systems modelling applied to environmental systems in the form of worked examples and case studies.
