Comment(by jdc):
I'm happy to rebase if needed.
Timing test on 2.2GHz Core2Duo running 32-bit Ubuntu 8.04:
Y=[[1,2,3,4],[5,6]]
time eY=e(Y)
time eY2=eY*eY
The second time is the one I'm looking to improve.
Before patch:
Time: CPU 0.56 s, Wall: 0.75 s
Time: CPU 1.93 s, Wall: 1.93 s
After patch:
Time: CPU 0.56 s, Wall: 0.75 s
Time: CPU 1.61 s, Wall: 1.61 s
I tested each change separately, and each showed an improvement in the
second time.
