Introduction to numerical linear algebra

Course offering missing for current semester as well as for previous and coming semesters
* Retrieved from Course syllabus DN2222 (Autumn 2009–)

Content and learning outcomes

Course contents

  • Well-posed and ill-posed problems and conditioning of problems
  • Rounding errors and numerical stability
  • Linear systems of equations: direct methods, sparse matrices
  • Singular value decomposition and its application in data analysis and information retrieval
  • Eigenvalue problems: theory, orthogonal transformations, iterative methods
  • Iterative methods for large linear systems: stationary iterations, Krylov space methods, preconditioning.

For each algorithm it is studied how it works, how many resources that are used as well as how good accuracy that can be expected in the results.

Intended learning outcomes

The overall goal of the course is to give you a deeper
understanding of the construction and functioning of modern software for problems. You will be able to select and utilize modern computing routines from a practical problem.

After the course you will be able to

  • identify linear algebra computations in a practical problem;
  • select appropriate algorithms;
  • perform such computations and estimate the computer resources needed;
  • judge the quality of the results, and
    implement special algorithms adapted to the problem at hand.

Literature and preparations

Specific prerequisites

Single course students: 90 university credits including 45 university credits in Mathematics or Information Technology. English B, or equivalent.

Recommended prerequisites

Basic numerical analysis, equivalent to DN1212 Numerical Methods and Basic Programmingor
DN1240 Numerical Methods Basic Course II and DN2221 Applied Numerical Methods, part 1. DN2221 is given in period 1 and period 2 so it is ok if you have started that course but not yet finished it.

Examination and completion

If the course is discontinued, students may request to be examined during the following two academic years.

Grading scale

A, B, C, D, E, FX, F


  • LAB1 - Laboratory Work, 3,0 hp, betygsskala: A, B, C, D, E, FX, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

In this course all the regulations of the code of honor at the School of Computer science and Communication apply, see:

Other requirements for final grade

Lab reports and written quiz (LAB1; 3 hp)

Opportunity to complete the requirements via supplementary examination

Ethical approach

  • All members of a group are responsible for the group's work.
  • In any assessment, every student shall honestly disclose any help received and sources used.
  • In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
