LINEAR ALGEBRA WITH SCIENTIFIC COMPUTATION | FMA421 |

**Aim**

The course aims at giving a basic treatment of linear algebra. Particular emphasis is on the role this plays in applications in different areas of technology, in order to give the future engineer a good foundation for further studies in mathematics as well as other subjects. The aim is also to develop the student's ability in problem solving and to assimilate mathematical text.

Furthermore, the course aims at giving basic ability in the use of computer software to convert mathematical theory into numerical computations. The students should become familiar with Matlab, its syntax and structures. The course is intended as a basis for other courses which use Matlab.

*Knowledge and understanding*

For a passing grade the student must

be able to represent, handle and compute with basic geometrical objects in three dimensions, such as points, vectors, lines and planes.

be able to show general knowledge of the matrix concept and its couplings to the concept of a linear transformation, and be able to carrry out elementary matrix operations and to solve matrix equations.

be able to give an overview of and illustrate mathematical concepts in linear algebra that are used to construct and study matematical models in the applications.

be able to explain the contents of some central definitions, theorems and proofs.

be able to use Matlab to carry out computations with concepts and objects from linear algebra.

*Skills and abilities*

For a passing grade the student must

in connection with problem solving be able to show capability independently to choose and use mathematical methods within linear algebra.

in connection with problem solving be able to show capability to integrate concepts from different parts of the course.

be able to show capability to explain mathematical reasoning in a structured and logically clear way.

be able to visualise mathematical results in Matlab.

be able to use basic computation methods in Matlab.
