Homework Problem Set 1: (download here) Due Friday 25 Aug 2006

 

There are a number of powerful software packages available for doing mathematics and data analysis on the computer.

We will use Igor Pro 5 and a free copy will be supplied to you by the instructor.

You may also want to take a look at Mathematica. Some simple examples of how Mathematica can be used are found here.

You can obtain Mathematica as a student at a greatly reduced rate. Licences arealso available for one semester or a year.

Importing and exporting data

Plotting

Curve fitting - linear and nonlinear regression
