This repository allows you to create parametric equation for arbitary images. The code itself was shamelessly copied from Wolfram Alpha Blog [1]. I basically stripped out the useless bits, and added a few lines so it spits out Matlab compatible equations. I also added a template, so you can basically copy the output from Mathematica, and paste it into Matlab, and plot the graph.
To run the code, open parametric_equation_generator.nb in Mathematica. If you want to generate code for Matlab, you need ToMatlab[2][3]. If you want to plot the generated Matlab code, you can copy them into plot_parametric_matlab.m.
