There's a growing number of packages written in Julia (http://docs.julialang.org/en/latest/packages/packagelist/ http://docs.julialang.org/en/latest/packages/packagelist/) and using the PyCall package you can call any python package if you're missing functionality. Do have a look to see if what you need is implemented. Other than that porting existing MATLAB code is extremely easy since the syntax is similar in many cases. Disclaimer: I'm one of the core devs.

One thing that is holding me back from porting my Matlab code to Julia is manual loop-unrolling. "It seems that, when using Julia, one needs to unlearn everything you’ve ever learned about vectorisation in MATLAB." [1]. Once the speed with Matlab-like syntax improves, I'll try again.

  > Once the speed with Matlab-like syntax improves, I'll try again. The @devec macro should help, meanwhile: @devec r = a .* b + c .* d + a ... will devectorize the expression. It's not perfect, but it's definitely useful. https://github.com/lindahua/Devectorize.jl https://github.com/lindahua/Devectorize.jl

Do you feel 2D plotting is sufficiently developed to be useful at this point?

  Sufficiently developed? No way. Is it getting there? Yes I think. There are no plotting facilities part of the standard library, but external packages like Winston [1] are available -- but the syntax was verbose for my taste, so I let it pass. According to this SO question[2], there was some web-REPL plotting earlier but it is unmaintained now.

    Agreed. If you are worried about the syntax for plotting, take a look at Gadfly, which aims to implements the Grammar of Graphics language for julia. https://github.com/dcjones/Gadfly.jl https://github.com/dcjones/Gadfly.jl

    You can also plot with Gaston, which is a frontend for gnuplot. https://github.com/mbaz/Gaston.jl https://github.com/mbaz/Gaston.jl Docs: https://bitbucket.org/mbaz/gaston/downloads/gastondoc-0.5.5.pdf https://bitbucket.org/mbaz/gaston/downloads/gastondoc-0.5.5....
