## Synopsis

### Functions/Subroutines

subroutine dlarnv (idist, iseed, n, x)
DLARNV returns a vector of random numbers from a uniform or normal distribution.

## Function/Subroutine Documentation

### subroutine dlarnv (integer idist, integer, dimension( 4 ) iseed, integer n, double precision, dimension( * ) x)

DLARNV returns a vector of random numbers from a uniform or normal distribution.

Purpose:

``` DLARNV returns a vector of n random real numbers from a uniform or
normal distribution.```
Parameters

IDIST

```          IDIST is INTEGER
Specifies the distribution of the random numbers:
= 1:  uniform (0,1)
= 2:  uniform (-1,1)
= 3:  normal (0,1)```

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.```

N

```          N is INTEGER
The number of random numbers to be generated.```

X

```          X is DOUBLE PRECISION array, dimension (N)
The generated random numbers.```

Further Details:

```  This routine calls the auxiliary routine DLARUV to generate random
real numbers from a uniform (0,1) distribution, in batches of up to
128 using vectorisable code. The Box-Muller method is used to
transform numbers from a uniform to a normal distribution.```
