Function/Subroutine Documentation

 

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:

N 

          N is INTEGER
         number of elements in input vector(s)


SA 

          SA is REAL
           On entry, SA specifies the scalar alpha.


SX 

          SX is REAL array, dimension ( 1 + ( N - 1 )*abs( INCX ) )


INCX 

          INCX is INTEGER
         storage spacing between elements of SX
