## Course Content

The topics that will be treated are listed below. For every topic, the relevant concepts are listed. Linear systems: linear system (consistent/inconsistent/homogeneous/inhomogeneous), (augmented) coefficient matrix, row equivalence, pivot position/column, (reduced) echelon form, basic/free variable, spanning set, parametric vector form, linear (in)dependence. Linear transformations: linear transformation, (co)domain, range and image, standard matrix, one-to-one and onto, singularity, determinant, elementary matrices. Subspaces and bases: subspace, column and null space, basis, coordinate system, dimension, rank. Eigenvalues and eigenvectors: eigenvalue, eigenvector, eigenspace, characteristic equation/polynomial, algebraic multiplicity, similarity, diagonalization and diagonalizability. Orthogonality: dot product, norm, distance, orthogonality, orthogonal complement, orthogonal set/basis, orthogonal projection, orthonormality, orthonormal basis, Gramm-Schmidt process, least squares problem/solution, orthogonal diagonalization, singular value/vector, singular value decomposition, Moore-Penrose inverse.

## Teaching Methods

The course is spread over a period of seven weeks. Each week there will be two theoretical classes of 90 minutes each and two exercise classes of 90 minutes each.

## Method of Assessment

There is a written exam at the end of the course.

## Literature
