Julia has first-class support for complex number arithmetic. Coupling this with powerful comprehension functionality allows you to easily perform complex computations. In this recipe, we will show how to plot a Julia set.
Make sure you have the PyPlot.jl
package installed. If it is missing run the using Pkg; Pkg.add("PyPlot")
commands in the Julia command line.
We would like to count how many iterations are required for repeated application of a mapping
to reach a value whose norm is greater than two. The number of iterations depends on the point from which we start the iterations. We will plot a heat map showing this relationship. You can find more details about the Julia set at http://mathworld.wolfram.com/JuliaSet.html or https://en.wikipedia.org/wiki/Julia_set.
In the GitHub repository for this recipe, you will find the commands.txt
file that contains the presented sequence of shell and Julia commands.
