====== How to do your homework in an IJulia notebook ======

1. Download the HW3 IJulia notebook file: {{:gibson:teaching:fall-2015:hw3.ipynb|}}

2. Start Julia. For me, it's like this. 

<code> 
gibson@timaeus$ ~/packages/julia-0.4.0/bin/julia
               _
   _       _ _(_)_     |  A fresh approach to technical computing
  (_)     | (_) (_)    |  Documentation: http://docs.julialang.org
   _ _   _| |_  __ _   |  Type "?help" for help.
  | | | | | | |/ _` |  |
  | | |_| | | | (_| |  |  Version 0.4.0 (2015-10-08 06:20 UTC)
 _/ |\__'_|_|_|\__'_|  |  Official http://julialang.org/ release
|__/                   |  x86_64-unknown-linux-gnu
julia>
</code>

3. Add the IJulia package to your julia installation, load the IJulia code into your running julia REPL, and then start a notebook.

<code>
julia> exit()
gibson@timaeus$ ~/packages/julia-0.4.0/bin/julia
               _
   _       _ _(_)_     |  A fresh approach to technical computing

   _ _   _| |_  __ _   |  Type "?help" for help.
