Low-rank approximation of analytic kernels

This repository hosts the MATLAB examples for the paper Low-rank approximation of analytic kernels by Marcus Webb https://arxiv.org/abs/2509.14017.

The file paper_figs.m produces all of the figures in the paper, in sequence. To produce the AAA-based approximations, you need to have Chebfun installed. To output the figures to tikz files you need the matlab2tikz package.
