#### Comments

Prerequisite for this course is knowledge of Advanced Calculus, Matrix Theory, Linear Algebraic Systems and Ordinary Differential Equations. The course will be adapted to the engineering point of view. That is, it will emphasize the mathematical interpretation and the corresponding formulation of the relative physical phenomena, avoiding any rigorous mathematical analysis. Numerous examples and applications will be the core of the course.
