The aim of the course is to present mathematical concepts and
methods from linear algebra and analysis which are important in
systems theory (continuous and discrete), and for further studies
within e.g. mathematics, economy, physics,
mathematical statistics, mechanics, control theory, signal theory
and for future professional work. The aim is also to develop the
student's ability to solve problems, to assimilate mathematical
text and to communicate mathematics.
Knowledge and understanding
For a passing grade the student must
- be familiar with the significance of eigenvalues in the context
of stability and resonance, in linear systems, with continuous as
well as discrete time.
- be able to describe and use the concepts of linearity, time and
space invariance, stability, causality, impulse response and
transfer function, in continuous as well as discrete time.
- be able to describe the structure of an exponential matrix,
and be able to compute exponential matrices in simple cases.
- be able to characterize different types of quadratic forms
using eigenvalue methods and via a completion of squares.
- be able to define the concept of convolution, continuous and
discrete, and to use convolutions both in the context of linear,
timeinvariant systems and in the description of certain types of
- have some experience and understanding of mathematical and
Competences and skills
For a passing grade the student must
- be able to demonstrate an ability to independently choose
appropriate methods to solve systems of linear differential and
difference equations, and to carry out the solution essentially
- be able to demonstrate an ability to use eigenvalue
techniques, elementary distribution theory, function theory,
Fourier and Laplace transforms and convolutions in problem solving
within the theory of linear systems.
- in connection with problem solving, be able to demonstrate an
ability to integrate knowledge from the different parts of the
- with proper terminology, in a well-structured manner and with
clear logic be able to explain the solution to mathematical
problems within the framework of the course.

Assessment: Written test comprising theory and problems. Assignments, requiring work with and without computer, which have to be completed BEFORE the exam.
The examiner, in consultation with Disability Support Services, may deviate from the regular form of examination in order to provide a permanently disabled student with a form of examination equivalent to that of a student without a disability.
