Follow-up Comment #19, bug #54342 (project octave):
Yes, muddled. That's why I wouldn't be worried about compatibility with its
v5 syntax.
The complicated part--and I'm not saying that this is a issue here, for the
reason I just stated--is that I thought I had read that Matlab's recent
behavior is to have just one r.n.g. for all such functions. Conflating
compatibility across the board will mean
octave:6> rand("state",0)
octave:7> randn("state",0)
octave:8> x1 = rand()
x1 = 0.84442
octave:9> x2 = rand()
x2 = 0.75795
octave:10> rand("state",0)
octave:11> x1 = rand()
x1 = 0.84442
octave:12> y1 = randn()
y1 = -1.2248
octave:13> x2 = rand()
x2 = 0.75795
isn't consistent; the calling of y1=randn() should alter the next outcome of
x2=rand().
