## Recommended Prerequisites

Mathematical Analysis, Linear Algebra and Computer Programming.

## Teaching Methods

The classes operate in two distinct modes: theoretical/practical master classes with students concentrated on a single class, and laboratory classes, where the students are divided into classes of 15 to 20 elements. In these laboratory classes, the students perform experimental and simulation works for testing the concepts acquired in master classes.

## Learning Outcomes

This curricular unit aims to present the students some fundamental computational tools, algorithms and techniques for solving problems in the area of electrotechnical engineering, which the students, as professionals, may come across.

The concepts will be introduced and exploited using MATLAB software. Thus, this curricular unit has also the objective of introducing this computer tool, which has a transversal usage in the most diverse areas of electrotechnical engineering, and with applications in advanced curricular units of the course.

At the end of this curricular unit, the students should be able to:

(i) Identify, analyze and solve a presented problem using the most appropriate computational tools;

(ii) Use MATLAB software to solve problems, either through built-in tools, already available with MATLAB, or through the implementation of algorithms and / or scripts.
