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.


The most updated version of the timetables can be found on the students' website:

You will find the timetables for all courses and degree programmes of Leiden University in the tool MyTimetable (login). Any teaching activities that you have sucessfully registered for in MyStudymap will automatically be displayed in MyTimetable. Any timetables that you add manually, will be saved and automatically displayed the next time you sign in.

MyTimetable allows you to integrate your timetable with your calendar apps such as Outlook, Google Calendar, Apple Calendar and other calendar apps on your smartphone. Any timetable changes will be automatically synced with your calendar. If you wish, you can also receive an email notification of the change. You can turn notifications on in ‘Settings’ (after login).

For more information, watch the video or go the the 'help-page' in MyTimetable. Pleas note: Joint Degree students Leiden/Delft have to merge their two different timetables into one. This video explains how to do this.

Mode of instruction

"There will be a weekly lecture and also a weekly problem session (tutorial). In order to help students judge their understanding of the material, there will be weekly tests, consisting of both homework and online quizes. 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.


From the academic year 2022-2023 on every student has to register for courses with the new enrollment tool MyStudymap. There are two registration periods per year: registration for the fall semester opens in July and registration for the spring semester opens in December. Please see this page for more information. An exemption is the fall semester for 1st year bachelor students, the student administration will enroll this group.

Please note that it is compulsory to both preregister and confirm your participation for every exam and retake. Not being registered for a course means that you are not allowed to participate in the final exam of the course. Confirming your exam participation is possible until ten days before the exam.
