• The code is documented in various files in the docs folder.

The figure above was generated with the following simple ChebPy code:

f = chebfun(lambda x: np.sin(x**2) + np.sin(x)**2, [0, 10])
g = chebfun(lambda x: np.exp(-(x-5)**2/10), [0, 10])
r = (f-g).roots()
ax = f.plot(); g.plot()
ax.plot(r, f(r), 'o')
