Introduction
Rather than re-invent the wheel, we'll use some tried and tested tutorial material. The following notes from the Maths department at the University of Dundee are concise, comprehensive, but also easy to read: http://www.maths.dundee.ac.uk/ftp/na-reports/MatlabNotes.pdf
We'll follow those notes, but will add in some more detail of our own in various sections. The section numbers and titles below will mirror those in the Dundee notes.
