[Octave-patch-tracker] [patch #10067] [octave forge] (linear-algebra) Improvement of funm

[Simon]

Follow-up Comment #3, patch #10067 (project octave):

thanks for your reply. On the General Discussion
<https://octave.1599824.n4.nabble.com/matrix-functions-td3137935.html> thread
is a link to Funm_files.tar (http://www.maths.manchester.ac.uk/~higham/NAMF/).
I looked at this code but in the thread you also find the following statement
by N.J. Higham: 
> [...] I don't have anything distributable due to funm being copyrighted by
The MathWorks. However, I think it's true to say that the state of the art
Schur-Parlett algorithm is fully described in the union of my various papers -
and in particular in my book [...]
I wasn't sure whether this statement includes Funm_files.tar. So I tried to
write the code from scratch based on the pseudocode in the book. But there is
still some resemblance to Funm_files.tar. 

The code at https://github.com/RickOne16/matrix is certainly better than my
implementation and should be used for future development. My approach was more
"experimental" than "professional". In particular, I didn't think about
vectorization, JIT etc..

Perhaps we can close this thread.
