If I have missed something - please, sent me mail with your homeworks or computer exercises. I will add these bonusponts to your examination grades. Examination is at 31 October and is moved from Väg och vatten to Maskinhuset. It is allowed to use on the examination notes written on the one side of A4-page. After 1 November I will put answers to the questions to "Examination". When I will check all examinations - I will inform about it on this page. Then ask personal in expedition about your grades. Good luck on examination!
All examination works written at 31.10.2014 (well done!) are verified and you can get information about your grades at expedition. Ask personal at expedition about information in LADOK.
Answers to the questions at examination are here:

I also thank all of You who have answered to the following course evaluation survey:
Course evaluation survey
This survey helps me get feedback from You and improve course for the next time.
Thus of You who have not yet filled it: I will be very grateful if You can fill it. You can sent this survey by mail or put it in the red box before my office. Thank You!
Numerical linear algebra problems arise in many different fields of
science like computational fluid dynamics, solid mechanics, electrical
networks, signal analysis, and optimisation. In this course we study
basic linear algebra concepts like matrix algebra, theory for linear
systems of equations, spectral theory, and vector- and matrix norms as
well as numerical aspects like efficiency, reliability, error analysis
and condition numbers. We consider three linear algebra building
bricks in computation:
- For solving linear systems of equations we present Gaussian
elimination with different pivoting strategies and blocking algorithms
for higher performance using BLAS (basic linear algebra
- For least-squares problems we study QR-factorisation and singular value decomposition.
- The methods for eigenvalue problems are based on transformation
techniques for symmetric and non-symmetric matrices.
For all three building bricks above we discuss numerical algorithms with respect to applicability, reliability, accuracy, and efficiency. By computer exercises the students get experiences in implementation and evaluation of numerical algorithms for linear algebra problems.
By the completion of this course the students will be able to:
- use numerical linear algebra as building bricks in computation.
- make a linear algebra model of problems from the physical reality.
- derive and use the numerical techniques needed for a professional solution of a given linear algebra problem.
- use computer algorithms, programs and software packages to compute solutions to current problems.
- critically analyze and give advice regarding different choices of models, algorithms, and software with respect to efficiency and reliability.
- critically analyze the accuracy of the obtained numerical result and to present it in a visualized way.
The course consists of 36 lecture hours, 20 exercise hours and gives 7.5 points.
The course code for engineering schools and students registered at Chalmers is TMA265. The course code for students registered in GU is MMA600.
All current and recent information will be
placed here. Regarding examination : CTH students should
not register for this exam. Only GU students can register for the
examination. CTH and GU students will get their personal exam numbers from
Observers of this exam. Examination usually is at Maskinhuset at
Where exactly (in which one
room) will be exam You will know at the day of examination: the
announcement will be placed at the blackboard close to the entree of
Maskinhuset. Notes: GU students can do re-examination but they can not
high their scores (for example, from G to VG) but Chalmers students
can do re-examination and high scores. Please, follow this site to get
exact information when and where will be re-examonation closer to the
day of re-examination.
The schedule for the course can be found via the link to
webTimeEdit top of the page.

The following sections in the textbook will be considered in the
book. Chapters 6 and 7 are saved for the another course.
- Chapter 1
mainly repetition and brief revision on basic linear algebra.
- Chapter 2
1-6, 7 except 2.7.4 and 2.7.5
- Chapter 3
- Chapter 4
- Chapter 5
The following questions in the textbook are recommended:
- Chapter 1: 1, 2, 3, 4, 5, 7, 13.
- Chapter 2: 3, 6, 7, 10, 11, 12, 17, 19.

To each chapter belong an optional homework assignment and a
computer exercise. The homework assignments are similar to the
questions in the textbook and such you could expect at the
examination. In the computer exercises you will be trained in using
different algorithms in numerical linear algebra using MATLAB or
PETSc libraries. Either you will use already existing MATLAB and
PETSC programs or write your own small MATLAB or PETSc codes. The
homework assignments give bonus credit points for the examination.
Since the occasions reserved for the computer exercises are without
supervision you may put questions on these exercises to me at the
lectures. Passed computer exercises will be graded with grades 3,
4, or 5, see examination below.
You may work in a group of 2 persons but hand in only one report for the group.
Wednesdays 13-15 (except the first week) in computer room MVF24 (Mathematical Sciences at Physics building)
Fridays 13-15 in computer room MVF24 (exept the first week when it is in room MVF25).
Hand in a short report of your work
before the final exam.
