1. TEST VALID
Hi,
Thanks to people who sends explanations or suggestions. In particular :
--Robert Craig for the analyse of the test.
--Daniel Berstein for the bibliography.

I noticed that srch=find(tstval,valid) is faster than
srch=find(tstval,{3,5,7,11}) thus isn't better programming to declare
constants,variables, sequences used in puts()?

Yes, it's the case. So any milliseconds fastest isn't a vital
question.

I agree, the main object of my test was curiosity and a good knowledge
of the "engine". Its very rare, as far as I am concerned, that I use a
500 000 loops in a routine.
