Hi, I’m trying to execute the code bellow. It was written in Julia 0.4.5 and I’m not sure if there is some part of it that is outdated.

# The error happens on line 10: save(“./EAData.jld2”,“X”,X,“U”,U,“D”,D,“Tend”,Tend)

Please [quote your code](https://discourse.julialang.org/t/psa-how-to-quote-code-with-backticks/7530). EDIT: And create a minimal example.
