[OctDev] randn() broken

[Justus P. <Jus...@UL...>]

Hi,

randn() from octave-forge-2004.09.09 (CVS version 1.11) appears to be
broken. The generated numbers are clearly not normally distributed:
Numbers near zero (the most likely numbers) are extremely rare, and
stretches of generated numbers appear to be sampled from different
distributions that vary from some 10s to some 1000s of numbers in
length.

See for yourselves by issuing

        plot(1:10000, randn(1, 10000), ".");

I have not tested later versions from CVS, but the CVS logs do not
suggest that this has been fixed. For my purposes, I'm reverting back
to the randn() from octave-2.1.57 whose output looks ok.
