This practical is a basic introduction to getting MATLAB started and evaluating some very simple mathematical expressions. You should begin by logging onto the Maths Dept. computer system by simultaneously holding down the control-alt-del keys. This will bring up a fresh login window with the name student. No password is necessary, just hit return and you will be logged on the system. The demonstrators will provide instructions on the board if you have trouble.

Once on the system you should start Netscape by double clicking on the icon. This will bring up the subject home page. Scroll to the bottom of the home page and click on the MATLAB introduction notes. You should then also open MATLAB by returning to the desktop and clicking on MATLAB. You can then switch back and forth between the two windows.

Assignment: Read to the end of the first 3 sections of the notes. This includes various subsections, such as 1.2. Then use MATLAB to evaluate the following expressions:

1. x = 0.5,
2. x = 1.5,

3. x = 2.5 + .5i,
