NAME
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
