random :: (MTRandom a, Vector v a) => MTGen -> Int -> IO (v a)Source
Return a random vector of length n
, filled with random elements
of type a
generated by the mersenne-twister.
E.g. to compute the sum of 100 million random Double values in a vector:
import qualified Data.Vector.Unboxed as U import System.Random.Mersenne import qualified Data.Vector.Random.Mersenne as G main = do g <- newMTGen Nothing a <- G.random g 10000000 :: IO (U.Vector Double) -- 100 M print (U.sum a)
