Purpose:

!>
!> DLARUV returns a vector of n random real numbers from a uniform (0,1)
!> distribution (n <= 128).
!>
!> This is an auxiliary routine called by DLARNV and ZLARNV.
!> 

Parameters

[in,out]	ISEED	!> ISEED is INTEGER array, dimension (4) !> On entry, the seed of the random number generator; the array !> elements must be between 0 and 4095, and ISEED(4) must be !> odd. !> On exit, the seed is updated. !>
[in]	N	!> N is INTEGER !> The number of random numbers to be generated. N <= 128. !>
[out]	X	!> X is DOUBLE PRECISION array, dimension (N) !> The generated random numbers. !>
