subroutine sscal ( integer  N,
real  SA,
real, dimension(*)  SX,
integer  INCX 
)

SSCAL

Purpose:
    SSCAL scales a vector by a constant.
    uses unrolled loops for increment equal to 1.
Parameters
[in]N
          N is INTEGER
         number of elements in input vector(s)
[in]SA
          SA is REAL
           On entry, SA specifies the scalar alpha.
[in,out]SX
          SX is REAL array, dimension ( 1 + ( N - 1 )*abs( INCX ) )
[in]INCX
          INCX is INTEGER
         storage spacing between elements of SX
