Linear Algebra

• 26 hrs lectures
• 26 hrs exercises

• 80 pts final exam
• 20 pts numeric exercises

The students will acquire an elementary knowledge of linear algebra and the ability to apply some of its basic methods in computer science.

The students will get familiar with elementary knowledge of linear algebra, which is needed for informatics applications. Emphasis is placed on mastering the practical use of this knowledge to solve specific problems.

Linear algebra is one of the most important branches of mathematics for engineers, regardless of their specialization, as it deals with both specific computational procedures and abstract concepts, which are useful for describing technical problems. The knowledge gained in the course is applied by graduates where engineering problems are written in  matrices, vectors and linear equations. The mastering of the basic concepts and their context will facilitate for further study and development of the chosen field.

Examples of tutorials are chosen to suitably complement the lectures.

• Evaluation of the five written tests (max 20 points). 

• Participation in lectures in this course is not controlled.
• The knowledge of students is tested at exercises  at five written tests for 4 points each and at the final exam for 80 points.
• If a student can substantiate serious reasons for an absence from an exercise, (s)he can either attend the exercise with a different group (please inform the teacher about that) or ask his/her teacher for an alternative assignment to compensate for the lost points from the exercise.
• The passing boundary for ECTS assessment: 50 points.

The minimal total score of 8 points gained out of the mid-term exams.
