MTH203 Numerical Methods (8)

This subject introduces students to a range of frequently used numerical algorithms. Consideration is given to the choice, theory, convergence, stability and implementation of the numerical procedures studied. Topics include error analysis, evaluation of functions, solution of nonlinear equations, difference calculus, curve fitting and data smoothing, numerical integration, numerical solution of differential equations, and systems of linear equations. Students are encouraged to code and test their numerical algorithms using a range of computational environments.
