Computation Resources for Linear Algebra Students

I have made a package in Julia to help ease some of the more computationally tedious aspects of the course. Your use of this resource is optional, but I have attempted to make it as convenient as possible.

1. Go to JuliaBox and login (you can use Google credentials, such as your Brown login)
2. Select “Julia 0.5.0” from the “New” pulldown menu in the top right
3. Type Pkg.clone("git://github.com/sswatson/IntroLinearAlgebra.jl.git") into the first cell and type shift+enter to run it
4. In the second cell type using IntroLinearAlgebra and type shift+enter to run it
5. You’re good to go! You can check out this tutorial notebook for examples you can copy and paste to get started. I have checked that that whole notebook runs smoothly on a fresh JuliaBox session. Since it intermingles installation with calculation; here’s a cleaner one showing a example session after you have everything installed.

If you don’t want to have to visit juliabox.com, Julia is easy to install on your own computer. You’ll also want to install the notebook interface IJulia, which is a bit less trivial but still doable. IJulia will still run in your browser, but it won’t be connecting to the internet (the content is served on your own machine).
