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)
