RedHat 9 (Linux i386) - man page for drscl (redhat section l)

DRSCL(l)					)					 DRSCL(l)

NAME
       DRSCL - multiplie an n-element real vector x by the real scalar 1/a

SYNOPSIS
       SUBROUTINE DRSCL( N, SA, SX, INCX )

	   INTEGER	 INCX, N

	   DOUBLE	 PRECISION SA

	   DOUBLE	 PRECISION SX( * )

PURPOSE
       DRSCL  multiplies  an n-element real vector x by the real scalar 1/a. This is done without
       overflow or underflow as long as
       the final result x/a does not overflow or underflow.

ARGUMENTS
       N       (input) INTEGER
	       The number of components of the vector x.

       SA      (input) DOUBLE PRECISION
	       The scalar a which is used to divide each component of x.  SA must be >= 0, or the
	       subroutine will divide by zero.

       SX      (input/output) DOUBLE PRECISION array, dimension
	       (1+(N-1)*abs(INCX)) The n-element vector x.

       INCX    (input) INTEGER
	       The  increment between successive values of the vector SX.  > 0:  SX(1) = X(1) and
	       SX(1+(i-1)*INCX) = x(i),     1< i<= n
