Code to reproduce the numerical experiments in the paper ``Multivariate rational approximation of functions with curves of singularities'' by Nicolas Boullé, Astrid Herremans, and Daan Huybrechs.
It requires the Chebfun software package in the MATLAB path, which can be downloaded from https://github.com/chebfun/chebfun.
The example file piecewise_diagonal.m requires in addition the UltraSEM package (https://github.com/danfortunato/ultraSEM).
