Purpose:

!>
!> DLARNV returns a vector of n random real numbers from a uniform or
!> normal distribution.
!> 

Parameters

[in]	IDIST	!> IDIST is INTEGER !> Specifies the distribution of the random numbers: !> = 1: uniform (0,1) !> = 2: uniform (-1,1) !> = 3: normal (0,1) !>
[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. !>
[out]	X	!> X is DOUBLE PRECISION array, dimension (N) !> The generated random numbers. !>
