[Q]: How to fill an array with random values?

[Gasper Tkacik]

Hello!

I am a first year graduate student at Princeton and am considering using 
Pooma for cosmological simulations. I have just downloaded and compiled 
it sucessfully and ran some very simple examples. I have the following 
question: how do I efficiently (without explicit looping) fill the array 
with random values?

I browsed through the manuals and the best I could come up with was to 
define a function Random, overload its () operator, create a
UserFunction<Random> rf and apply it to the array A like this

A = rf(A);

However, I do not know if this is a good solution. Random does not need 
any parameter, but I was forced to put in something to conform to the () 
syntax, so I just put in the same A array. Is there a more elegant 
solution? I hope the compiler does not generate a temporary copy in the 
above example?

BTW: Is this list appropriate for such questions or are there only 
development issues discussed? If the later, I apologize.

Best regards, Gasper.
