## Synopsis

### Functions/Subroutines

subroutine slaruv (ISEED, N, X)
SLARUV returns a vector of n random real numbers from a uniform distribution.

## Function/Subroutine Documentation

### subroutine slaruv (integer, dimension( 4 ) ISEED, integer N, real, dimension( n ) X)

SLARUV returns a vector of n random real numbers from a uniform distribution.

Purpose:

``` SLARUV returns a vector of n random real numbers from a uniform (0,1)
distribution (n <= 128).

This is an auxiliary routine called by SLARNV and CLARNV.```
Parameters:

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. N <= 128.```

X

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

Further Details:

```  This routine uses a multiplicative congruential method with modulus
2**48 and multiplier 33952834046453 (see G.S.Fishman,
'Multiplicative congruential random number generators with modulus
2**b: an exhaustive analysis for b = 32 and a partial analysis for
b = 48', Math. Comp. 189, pp 331-344, 1990).

48-bit integers are stored in 4 integer array elements with 12 bits
per element. Hence the routine is portable across machines with
integers of 32 bits or more.```
