Assumed knowledge: The following core first and second year modules are particularly important:

Useful background: Some knowledge of numerical concepts such as accuracy, iteration and stability as provided in MA261 Differential Equations: Modelling and Numerics will become important in the context of this module. General interdisciplinary curiosity will also be supported through interactions with areas such as medical imaging and data science.

Synergies: The following modules link up well with Matrix Analysis and Algorithms, either through methodology, computational or application-oriented content:

Leads to: The following modules have this module listed as assumed knowledge or useful background:

Content: Many large scale problems arising in data analysis and scientific computing require to solve systems of linear equations, least-squares problems, and eigenvalue problems, for which highly efficient solvers are required. The module will be based around understanding the mathematical principles underlying the design and the analysis of effective methods and algorithms.

Aims: Understanding how to construct algorithms for solving some problems central in numerical linear algebra and to analyse them with respect to accuracy and computational cost.

Objectives: At the end of the module you will familiar with concepts and ideas related to:

  • Various matrix factorisations as the theoretical basis for algorithms
  • Assessing algorithms with respect to computational cost
  • Conditioning of problems and stability of algorithms
  • Direct versus iterative methods.
