Julia package for Fatou sets. Install using Pkg.add("Fatou") in Julia. See Explore Fatou sets & Fractals in Wiki for detailed examples. This package provides: fatou, juliafill, mandelbrot, newton, basin, plot, and orbit; along with various internal functionality using Reduce and Julia expressions to help compute Fatou.FilledSet efficiently. Full documentation is included. The fatou function can be applied to a Fatou.Define object to produce a Fatou.FilledSet, which can then be passed as an argument to the plot function of PyPlot. Creation of Fatou.Define objects is done via passing a parse-able function expression string (in variables z, c) and optional keyword arguments to juliafill, mandelbrot, and newton. Fatou also provides basin to display the the Newton / Fatou basins using set notation in LaTeX in IJulia.
