ASTR 40100 Practical Data Analysis

We are meeting in the Mac classroom at the back of the computer area in the basement of Crerar library on Wednesday mornings from 9 to 12.

We are using the Matlab program with is made by Mathworks. This is a similar program to IDL but perhaps better. Matlab stands for "Matrix Laboratory" - it was originally written to provide an interactive interface to the powerful LAPACK matrix manipulation libraries. To run matlab login to cpteach.uchicago.edu and type "matlab" - this will get you the terminal style prompt which I like. If you insist there is a gui type interface which can be had by typing "gmatlab".

Help can be had by typing "help command-name" at the terminal prompt. There is help available inside the gui. Help is also available on Mathworks website.

I recommend to use the editor emacs which can be started by typing "emacs". A geek bonus when using emacs is that matlab program files appear auto colorized.

Here are notes from each class:

Here is the command to run before Matlab to fix the problem with using external "mex" plugins:

setenv LD_PRELOAD /lib/libgcc_s.so.1
The above is not necessary any more
