MAS212 Scientific Computing and Simulation
|Semester 1, 2017/18||10 Credits|
|Lecturer:||Dr Sam Dolan||Home page||Reading List|
The module further develops the students’ skills in computer programming and independent investigation. The students will learn how to solve algebraic and differential equations using Python. The students will learn basic numerical methods, and methods to visualize and analyse numerical results. The students will apply the knowledge to explore the physical behaviours of model equations.
Prerequisites: MAS115 (Mathematical Investigation Skills)
Corequisites: MAS211 (Advanced Calculus and Linear Algebra); MAS222 (Differential Equations)
The following modules have this module as a prerequisite:
|MAS316||Mathematical modelling of natural systems|
|MAS414||Mathematical Modelling of Natural Systems|
