Hi guys,
please help me.
When I range a number in gaussian distributions I use: Fo=abs(f+10*(randomn(seed,60))).
But now I would to range Fo value between 0.5 and 1, but not as gaussian distribution. How can I do?
Cheers, Christina
ps. Happy New Year!!!!

f0 = cgScaleVector(RandomU(seed, 60), 0.5, 1.0)

Or, maybe this, depending on what you are looking for:
f0 = RandomU(seed, 60)* 0.5 + 0.5

Thank you, Mr Fanning!
I think the last solution is the best for my work. In this way I'm sure that f0 range between the min value 0.5 and the max 1 (not with a gaussian distribution), isn't it?
Cheers,
Christina
