Is there any fast way to compute the barycentric Lagrange interpolation using matlab?

  • Consider asking at [scicomp.se] –  Jul 18 '14 at 21:30
  • What is your setup here? An affine interpolation from values specified at the vertices of a reference simplex? Or something else? – hardmath Jul 19 '14 at 00:18
  • In addition to the information hardmath requested, you should specify what you mean by "fast." (Or, at least, the size of your dataset.) Contrary to what some may think, though, software of use to mathematicians IS on-topic on this site per the FAQ. – apnorton Jul 19 '14 at 00:34

    I am trying to use Lagrange interpolation for chebyshev nodes. I know that Barycentric method is a fast implementation of Lagrange interpolation. Is there any other way which be faster? – user3482383 Jul 19 '14 at 09:45
