You can also see it in the SandMath manual  the most recent version is available at TOS, search for SandMath  and an older version is available here: http://systemyde.com/pdf/SANDMATH44_3x3_Manual.pdf Incidentally I also implemented the same approach on the 41Z module using complex math routines  not 13digit accurate unfortunately but still holding very nicely given the task to perform. It is an ALLMCODE version as well. Thanks for sharing the link to Dr. Pugh's work, very enjoyable.
