Exercises

We will be using the open  software Octave (https://www.gnu.org/software/octave/), which can be downloaded here (free)  : https://www.gnu.org/software/octave/download.html

For what we will be doing, the language is the same as MATLAB, so you are free to use either of the two softwares.

For the students who have never used Matlab/Octave, we advise to do the introduction session below, which is written for Matlab but fully compatible with Octave.

Please bring your own laptop with you for these exercise session.

Project

For the project, we will be using a combination of Matlab/Octave and the finite element softwre FinElg, see instructions to install here
