I don't think this is really a good comparison. Matlab is a $150 for a personal license for the language itself ($1000/year for commercial), and if you want any packages, all the packages are extra on top of that. Julia is fully open source, and has a strong open source package ecosystem (I think we're up to 10k packages by now). Juliahub provides some enterprise systems like JuliaSim, but the language itself is totally free.
