Symata.jl is a symbolic math language. (The old name was SJulia.) You can add it with Pkg.add("Symata.jl"). The site is https://github.com/jlapeyre/Symata.jl
Notebook examples are here https://github.com/jlapeyre/Symata.jl/tree/master/examples (the math looks better in live Jupyter sessions) To try the latest features, you need to use the development version using Pkg.checkout("Symata") after adding it. Among the New Things: * Builds and tests on Linux, OSX, and Windows using Travis and Appveyor. * Installation is much easier, using Steven Johnson's PyCall recipes. * Works in Jupyter notebook using IJulia.jl (It typesets the math using LaTeX). Symata still works at the command line REPL as well. * A few tutorial notebooks are included. They cover a small fraction of Symata. * ... oh, and rudimentary plotting via Plots.jl. This could be expanded with little effort. Please file an issue on github, https://github.com/jlapeyre/Symata.jl, if you have any problems or suggestions.
