Installation (specific to lab 1 FRTN35: Frequency response analysis)

0. If you run on your personal computer, you might need to install Julia. Download and install Julia v1.0+ from julialang.org. If you prefer a "batteries included" approach with an IDE, download and install the free version of Julia Pro.
1. Open a terminal
2. Type mkdir FRTN35_lab1; cd FRTN35_lab1
3. Paste the following in a terminal

printf 'export JULIA_DEPOT_PATH=/var/tmp/$USER\n' > julialab1
printf 'export JULIA_EDITOR=gedit\n' >> julialab1
printf 'julia\n' >> julialab1
chmod +x julialab1

(Feel free to choose another text editor if you don't like gedit.) This step only needs to be done once. Henceforth you can start julia with the environment setup by running ./julialab1 in the current directory. 4. Start ./julialab 5. Install BallAndBeam.jl using command using Pkg; Pkg.add("https://gitlab.control.lth.se/processes/BallAndBeam.jl.git"); using BallAndBeam Lots of packages will now be installed, this will take some time. 6. Type cp(joinpath(pathof(BallAndBeam),"src","FRTN35_lab1.jl")), "FRTN35_lab1.jl"); edit("FRTN35_lab1.jl"). The script FRTN35_lab1.jl will now open in the chosen text editor, edit it while following the lab manual. If unsure about how a function works, type ?function_name for help. 7. Run Pkg.activate(pathof(BallAndBeam)) to install further required packages.

Test

Run, the following commands and see if tests pass (it may take a minute)

julia> Pkg.test("BallAndBeam")
