# Mathematical Methods Course Notes

Lecture notes from my MSc course on mathematical methods.

The aim was to give an overview of various mathematical techniques and algorithms, likely to be of use to people doing research, particularly in computer vision and bioinformatics. The intention is not to go into tremendous detail on each method, but to give enough information so that students get the general idea of the approaches, and an understanding of the situations in which each algorithm would be useful.

The recommended course textbook is "Numerical Recipes in C" (or more recent variants) by Press et al. which gives an excellent overview of many useful techniques.

It was recommended that the course assignments were done in MatLab.
