The course has two main goals. The first one is to introduce the main topics of linear algebra and geometry, training the student to follow logical deductive arguments and to use the proper formal language. The second goal is to give to the students the main concepts of some basic numerical methods of linear algebra and of their implementation in MATLAB, which is by now widely used in engineering. The course will show how theoretic, symbolic and numerical aspects interact with each other.

The second goal is to give to the students the main concepts of some basic numerical methods of linear algebra and of their implementation in MATLAB, which is by now widely used in engineering. The course will show how theoretic, symbolic and numerical aspects interact with each other.

This course wants to develop the student's ability to understand logical arguments stressing the role of the hypothesis, for example by building examples and counterexamples. The student acquires tools and techniques to work with geometrical objects (vectors in the plane and i the space, lines, planes, conics and quadrics) and with algebraic objects (linear systems of equations, matrices, polynomials, eigenvalues, eigenvectors, vector spaces and their transformations). For example, the student is able to symbolically deal with a linear system of equations and to compute its solutions: these solutions can correspond to the intersection of two lines, to the eigenvectors of a matrix or to the circles passing through two points. The student will also acquire the necessary knowledge to numerically solve some basic problems in linear algebra (for example, computing the solutions of a linear system of equations and computing the eigenvalues of a matrix). These problems usually arise as an intermediate, or final, step in solving more complex problems which can not be treated with analytical methods. In particular, the student learns to identify, among the presented methods the one giving the most accurate solution with the least computational cost. The use of the software MATLAB is crucial to reach these goals.

Practical sessions
Practical sessions will work on the arguments of the lectures. Some practical sessions will be held by the teaching assistant solving problems and some will require the active participation of the students. Moreover, there will be computer aided sessions in which the methods presented during the lectures will be used with the help of the software MATLAB. The goal of the practical sessions is a better understanding of the methods presented during the lectures and to give a critical analysis of the obtained solutions.

The exam will check both theoretical knowledge and practical skills acquired by the student. The exam will consist in a computer assisted test and in a written exam. During the test and the written exam it is forbidden to use books, notes and all not authorised material. The computer test consists of multiple choice questions, most of them to be solved using MATLAB. The computer test takes 45 minutes and contributes up to 30% of the final grade. Wrong answers are penalised. There exists a minimal threshold of correct answers under which the student cannot take the written exam and fails the exam. The written exam consists of multiple choices questions and one exercise. The written exam takes 1 hour and contributes up to 70% of the final grade. There exists a minimal threshold of correct answers under which the student fails the exam. An additional oral test can be sustained at the professor's discretion. To pass the exam, the student must attend both parts (computer assisted and written), score the minimal number of required points, and the sum of the two grades (computer assisted + written) must be at least 18.
More details will be given during the lectures and will be posted on the web page of the course.
