Do you know of any open source packages for doing multi-dimensional Chebyshev regression? I have seen coefficient determination only when the function is known, and one guide for how to do collocation in one dimension, but not really for a ‘best-fit’ in an overdetermined system.
- cozzyd 8y agoI don't, other than attempting to use a general minimization package, which I would expect not to work so well without hand tuning of initial guesses. I think gsl and chebfun (matlab, unfortunately) can do regression in one dimension but I don't think it can in 2 or 3d (much less general high dimensions).
