## Synopsis

### Functions/Subroutines

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

## Function/Subroutine Documentation

### subroutine slarnv (integer idist, integer, dimension( 4 ) iseed, integer n, real, dimension( * ) x)

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

**Purpose:**

SLARNV 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 REAL array, dimension (N) The generated random numbers.

**Further Details:**

This routine calls the auxiliary routine SLARUV 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.
