# Introduction

Last revision: May 09, 2016Welcome to the **tutorial on numerical computation** for undergrads
in Physics, Maths and Engineering.

The aim of this tutorial is to learn to *do mathematics with the
computer*. In real life applications of mathematics, most of the
time the calculations are too hard to be completed with pencil and
paper. Thus, we will learn how to use a computer to help us.

In order to take the tutorial you will need to have access to a
computer with `GNU-octave`

installed. The first node of the
tutorial provides some help with the installation. Luckily, it
is *free software* It runs on Linux, MacOS, Windows… it even
runs on Android!

Follow the tutorial with the octave window open: learning to program without access to the software is a frustrating experience. Whenever you have questions, you may ask me, either by e-mail or personally.

This webpage offers an online octave window… try it!
