for n-dimensional vector spaces?
I found some pseudo-code, see page 15 (in section 3 "affine diagonalization" which begins on page 12) of
- [Lecture 21: Surfaces](https://cs.nyu.edu/yap/bks/egc/09/21Surfaces.pdf) in [Robust geometric computation](https://cs.nyu.edu/yap/bks/egc/)
Searching online led me also to this answer from 2008 where someone does it with Maple:
- [Maple primes: Normal forms for quadratic functions](https://www.mapleprimes.com/posts/38766-Normal-Forms-For-Quadratic-Functions)
but unfortunately, I cannot open the `.mws` file (I get an error message concerning the version number).
Thank you very much for the help.BernMon, 18 Jan 2021 19:59:25 +0100https://ask.sagemath.org/question/55345/
