This is a testbed for a generalization of κ-curves, called extended- or ϵ-κ-curves.
First download and install Julia. Then in the Julia shell:
julia> using Pkg;
julia> Pkg.add("Polynomials");
julia> Pkg.add("Gtk");
julia> Pkg.add("Graphics");
The above steps may take some time to finish.
Also download and extract this repository.
In the Julia shell:
julia> cd("c:/path/to/ekcurves");
julia> include("ekcurves.jl");
julia> EKCurves.run()
(You can skip the first step if you start Julia from the ekcurves
directory.)
The GUI is quite self-explanatory.
(Note that since Julia uses Just-In-Time compilation, the program may be slow when you start to use it, but then it will speed up..)
