Linear Algebra for Computer Scientists 1


Admission requirements

Not applicable.


In this course we introduce matrices as a tool for representing and solving systems of linear equations. The process of row reducing a corresponding matrix into reduced echelon form is studied. Various properties of matrices are studied as well, such as the determinant, algebraic operations (matrix multiplication and the inverse of a matrix), and the relation of matrices to lineair transformations.

Course Objectives

To gain insight into mathematical methods and techniques concerning linear systems and linear transformations. Studying applications of linear systems in network flow problems and applications of the determinant in graph theory.

Mode of instruction

There will be a weekly lecture and also a weekly problem session (tutorial). As part of the problem session there will be a short test each week, to help students judge their understanding of the material. During the problem sessions the students also have the opportunity to ask questions about the material covered so far.

Assessment method

As well as the weekly tests, there will be a final examination. The final grade for the course will be an average of the grades from the weekly tests and the grade for the final exam; the exam will count for 75%, and the tests for 25%.

The lecturer will inform the students how the inspection of and follow-up discussion of the exams will take place.

Reading list

David. C. Lay: *Linear Algebra and its Applications, Addison-Wesley. *
This book will be required for the course; weekly problem sessions will be based on it, and essential reading will be set from it. The 5th international edition is recommended, but other editions are also OK, just be aware that the page numbers for the required reading may be incorrect.
