Hello,

Can I use a multi-interval domain for `EvalChebyshevFunction`

?

I want to approximate (\frac{\sin(\pi x)}{\pi x}) with polynomials, and the values of (x) would be near integers.

Specifically, all (x) would be in the intervals ((i-\epsilon, i+\epsilon)) for (i = -N, \ldots, 0, \ldots, N).

In this case, if I use a long interval like [-N, N], it causes a lot of noise.

Can you give me some advice on how to deal with this issue?

I want to know if I can use multi-interval approximation as in the bootstrapping procedure.

Thank you.
