This page is to be filled with graphical tools.

I still have to find out how to upload files (programs).

I usually use IDL - Interactive Data Language - to make plots and analyze data. This should be available on the physics computers. You can buy your own student version to use on your private computers, but I think it might be a rather big investment.

ITT send me a link to their online resources with tutorials at http://www.ittvis.com/ProductServices/IDL/IDLTutorials.aspx.

Getting Started

Edit the output file (we assume a file name output.txt)from EZ so it contains six header lines, followed by the data lines. Make sure that you used ez_example.f as starting point for your program modifications.

To read the data file, use the IDL program readmatrix.pro.

The first parameter gives the name of the matrix, the second the name of the file to load. We use an optional parameter ``o=6`` to skip the first six lines.

IDL> readdmatrix,a,'output.txt',o=6
