vconj :: Int -> Ptr a -> Int -> IO ()

Replaces y with conj y.

acxpy :: Int -> a -> Ptr a -> Int -> Ptr a -> Int -> IO ()

Replaces y with alpha (conj x) + y

vmul :: Int -> Ptr a -> Int -> Ptr a -> Int -> IO ()

Replaces y with x*y.

vcmul :: Int -> Ptr a -> Int -> Ptr a -> Int -> IO ()

Replaces y with conj(x)*y.

vdiv :: Int -> Ptr a -> Int -> Ptr a -> Int -> IO ()

Replaces y with y/x.
