🌳 Plotting the roots of monic Littlewood polynomials in MATLAB

Littlewood

Plotting roots of monic Littlewood polynomials (and monic polynomials with coefficients of 1 and other numbers).

Explanation

Littlewood polynomials are polynomials with coefficients of either 1 or -1. Monic polynomials have the first coefficient as 1. This script plots the roots of every N-th degree monic Littlewood polynomial on the complex plane.

Usage

The two main functions are find_roots(polynomial_order, other_no) and render(image_name, points, plot_centre, plot_scale, image_size) where the points argument is the output of the first function.
