module Data.Vector.Random.Mersenne

-- | Return a random vector of length <tt>n</tt>, filled with random
--   elements of type <tt>a</tt> generated by the mersenne-twister.
--   
--   E.g. to compute the sum of 100 million random Double values in a
--   vector:
--   
--   <pre>
--   import qualified Data.VectorUnboxed as U
--   import System.Random.Mersenne.Pure64
--   import qualified Data.Vector.Random.Mersenne as G
--   
--   main = do
--       g &lt;- newPureMT
--       let a = G.random g 10000000 :: U.Vector Double
--       print (U.sum a)
--   </pre>
--   
--   The generator will fuse under stream fusion, so e.g. sum . random g
--   will allocate no intermediate array.
