NAME

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/SRC/drscl.f

SYNOPSIS

Functions/Subroutines


subroutine DRSCL (n, sa, sx, incx)
DRSCL multiplies a vector by the reciprocal of a real scalar.

Function/Subroutine Documentation

subroutine DRSCL (integer n, double precision sa, double precision, dimension( * ) sx, integer incx)

DRSCL multiplies a vector by the reciprocal of a real scalar.

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.
!>

Parameters

N 

!>          N is INTEGER
!>          The number of components of the vector x.
!>

SA

!>          SA is 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

!>          SX is DOUBLE PRECISION array, dimension
!>                         (1+(N-1)*abs(INCX))
!>          The n-element vector x.
!>

INCX

!>          INCX is 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
