dlarnv

dlarnv.f(3)							      LAPACK							       dlarnv.f(3)

NAME

       dlarnv.f -

SYNOPSIS

   Functions/Subroutines
       subroutine dlarnv (IDIST, ISEED, N, X)
	   DLARNV

Function/Subroutine Documentation
   subroutine dlarnv (integerIDIST, integer, dimension( 4 )ISEED, integerN, double precision, dimension( * )X)
       DLARNV

       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.
