> I compared several different methods of generating polynomials of different sizes for speed and precision (spoilers: taylor series were the worst and minimax polynomials (Remez algorithm) were the best). I would have expected at least an LSQ approximation with a basis of Legendre polynomials thrown into the mix. I got that as a basic homework in my numerics class once, after we've shown to ourselves in the class that [1, x, x², x³...] is not a really good basis to project things onto. |
