Re: BZSUPPORT: Normal random distribution

[Todd V. <tve...@ex...>]

Normal<T> wants these constructor arguments:

    Normal(T mean, T standardDeviation)

If you want a unit normal distribution, use the class
NormalUnit<T>.

See
http://oonumerics.org/blitz/manual/blitz08.html#index00442

Cheers,
Todd
