**5. Matrices: **Further Resources

### Online Resource Collections

MathTutor and mathcentre have rich collections of free online resources on a variety of topics in mathematics aimed at bridging the gap between school and university study. The coverage of topics is much more thorough than in this course and you can use these as a source of written handouts, additional exercises and videos on the topics covered here, but also as a source of resources on topics beyond the scope of this course.

Below you can find links to topics that are particularly relevant to the section on Matrices.

Maths E.G has a rich and extensive collection of computer-based questions and quizzes on a variety of topics within mathematics and statistics. While covering a much more thorough set of topics than this course, some of the exercises there (in particular, the collection on Matrices as well as the example of Markov chains in the collection on Economics) are highly relevant to this section.
