Just my experiments with MSVC 5.0: without optimalization my code runs correctly
(give same results as MATLAB), with optimization ON it gave incorrect results...

Some months ago I read in DDJ (Dr. Dobbs Journal) an interview with the man who
created or helped to create the first math co-processor. He said the the
floating point optimizations in MSC are inferior and although they speeds things
up, they lead to incorrect results. It seems to me he was right...

Question #7: How Can I Make Linux More Like Windows?

'Hmmm. Rebuild the kernel to use every memory-hogging feature you can find.
Reboot every
couple of days whether you need to or not. And every 18 months or so, send a
check for $99
to Bill Gates. That should do the trick.' (CNET - 10 questions about Linux
[4.28.1999])
