You don’t want to explicitly calculate &quot;node poly&quot;. The formula you want is the “second barycentric formula”, (4.2) at the top of page 505 of https://people.maths.ox.ac.uk/trefethen/barycentric.pdf Or formula (2.6) halfway down page 2 of https://people.maths.ox.ac.uk/trefethen/publication/PDF/2011... Also cf. Higham (2004) “The numerical stability of barycentric Lagrange interpolation” https://www.maths.manchester.ac.uk/~higham/narep/narep440.pd... If you want to implement the “first barycentric formula” instead you need to take some additional care to avoid…</p><p><a href="https://hackerpaper.kaipfister.de/p/1612.00337/">Paper and discussion history</a>.
