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, also using a computer, some basic problems in linear algebra when the “pencil and paper” method is not feasible (for example, computing the solutions of a large linear system of equations and computing the eigenvalues of a matrix). In particular, the student learns to identify an algebraic/geometric object, to recognize its theoretical properties and to choose the most fit algebraic/geometrical method to deal with the object. The implementation and the application of the numerical methods is done using the software MATLAB of which the student learns the basic aspects.

Modalità di esame: Prova scritta a risposta aperta o chiusa tramite PC con l'utilizzo della piattaforma di ateneo Exam integrata con strumenti di proctoring (Respondus);
The exam will check the theoretical knowledge of the material of the course and the ability of applying the theory in a practical context. It will also be checked the ability of the student of choosing and applying a numerical method depending on the explicit example. Thus the exam will focus on both theoretical both applied aspects of the course and will be performed using a PC assisted test using both open both closed questions. The test consists of 14 questions of which 10 are on the theoretical part and 4 are on the applied part. The test had a duration of 75 minutes and has a value of 33 points; each question has the same value. Each multiple choice question has 4 alternatives of which only one is correct; each wrong answer has a penalty of 15% of its value and not answering gives 0 points. The teacher can ask the student to take an oral test (only in the case that the student of at least 18 points) to further test the theoretical knowledge of the student. During the test it is forbidden to use books, notes and not authorised electronic devices. The above described test will be performed using the platform Exam with a proctoring system (Respondus).
Exam: Computer-based written test with open-ended questions or multiple-choice questions using the Exam platform and proctoring tools (Respondus);
