Duh, I forgot to replace the Function.

Here it is, I changed the font size so it fits in one screen: SET OUTPUT FONT SIZE 12

This is what I get.

I had to run the program 32 times to get any errors, and this is my first screen with errors:

You are running on an iPad Pro, I believe. That accounts for being able to increase the font size. Your speeds are quite a bit faster than mine and Henk's. I'm not sure how to account for the improved accuracy. Is there better math processing on the Pro?

No, i lowered the bias that you added to the mat_mul function untll i got no more "erroneous" matrices in 10 runs, but stated that that bias was not a guarantee on a "clean" unit matrix.
George just did more runs and proved that statement, using 32 runs.
