Teaching methods

Lectures and exercises in the computer laboratory. The exercises consist in the analysis / development and use of Matlab scripts, concerning the numerical methods proposed in class. The exercises will be guided by the teacher and aimed at a better understanding of the theory as well as increasing the student's computational skills.

Assessment methods

The exam consists in an oral discussion on the topics dealed with during the lessons and on the exercises carried out by the student during the course.

Teaching tools

Teacher's pantries on some topics, slides and Matlab code
