go in CAS and create a 50*50 random, floating point matrix:
randmat(50,50)*0.1

Then try inverting it using
Ans^-1

you will get an even larger boost there.

I inverted a 100x100 matrix on the G2 in 3.645 seconds. A Philco 2000 ad from November 1961 shows that the Philco 2000 could invert a 100x100 matrix in 60 seconds and the computer was a room-sized machine. Whew!

100x100 matrix inverted in 21s on G1 Rev C!
