Re: Randomly initializing a N-element vector

[Russell J. Abbott]

Off the top of my head, how about this:

Generate N-1 random numbers between 0 and 1.  Sort them.
Preceed the first by 0 and follow the last by 1.
Take the differences between the elements in the extended
sorted result.  Permute those differences randomly.

Each difference is between 0 and 1.  The total sums to 1.
