I am somewhat puzzled about what exactly is happening when computing derivatives and conversions on 2d Chebyshev product spaces. Some enlightenment would be greatly appreciated. This is also related t…

The ones that are particularly bad are worley-linear-range, worley-manhattan-range, and worley-chebyshev-range. The ones that fall within [-1,1] but don't hit it exactly (such as worley-linear-squared…

In lecture16, here are several codes:
S₀ = I : Chebyshev() → Ultraspherical(1)
f = Fun(exp, Chebyshev())
g = S₀*f
g(4) - exp(4)
I found the error when I run it:
UndefVarError: I not defined

This simple test gives a NaN result:
using ApproxFun
xdom = Chebyshev(-1..1)
x = Fun(identity, xdom)
N(u, v) = [u - x; v + x]
u0 = 0*x
v0 = 0*x
