Projects
Directions for the Projects
Staple all sheets of your projects together. Be sure to include your code and output.
Matlab Output
If you put all your code in a .m file then instead of printing out your code
and its output, you can use Matlab's publish option. Using Publish:
- write the .m file
- run & test your code
- click on the window your code is in
- go to the file menu
- click on publish your_file_name.m
- print or email me the published file
The published file should be an html file by default. It will include all your
code and the output in one file. If you want to change the format of the file,
you will need to change your configurations. If you want to figure out how to
give your published file special formatting like headers, titles, lists, comments,
etc. look at Matlab's help feature.
For several of these projects, you will need to use some of the programs in the
Laydata toolbox.
To access these files, click on the link above, select Data Files from the menu on the left, and download the zipped folder.

LU Factorization using Matlab
If you want to use matlab for LU factorization, you will want to download the function
LUfactorization.m
To use this function:
- open the .m file
- copy and paste it into matlab (not the command window but into the editor
- save it (when you hit save it will automatically save it as LUfactorization.m)
- type in the matrix A you want to factor
- type: [L,U]=LUfactorization(A)
To see how the function works, open the file and read the comments.
Accessing Matlab
- Fretwell 319
- A linux lab open MTWR 8am-8pm and F 8am-5pm. All machines have matlab installed on them.
- Barnard Lab(s)
- Only the 2 linux computers have Matlab installed on them. This lab is open 24/7.
- Woodward 335
- This lab can be accessed if your major is in the CCI (college of computing and information) or if you are taking a course in the CCI. There are Macs, PCs, and linux boxes. As of last week, only the PC's had matlab installed on them.
- A Mosaic Account
- This is an option only if your major is in the College of Engineering.
- Purchasing Matlab
- The student version costs around $99, and the best places I've seen to buy it are from SIAM or JourneyEd.
