Talk:Gauss-Jordan matrix inversion
what's wrong (with REXX)?
My REXX algorithm works nicely most of the time. But sometimes it fails. E.g., with this matrix:
3 1 8 9 6 6 2 8 10 1 5 7 2 10 3 3 2 7 7 9 3 5 6 1 1
The first elimination sets a.2.2=0 and how could this become 1 furtheron? Help! Thanks!! --Walter Pachl 08:52, 3 November 2018 (UTC)
