     void cscal( n, a, x, incx )
     Integer	       incx, n;
     Complex	       a;
     Complex	       (*x)[ n ];

     void zdscal( n, a,	x, incx	)
     Integer	       incx, n;
     double	       a;
     Complex	       (*x)[ n ];

     void csscal( n, a,	x, incx	)
     Integer	       incx, n;
     float	       a;
     Complex	       (*x)[ n ];


DESCRIPTION    [Toc]    [Back]

     dscal, sscal, zscal, cscal, zdscal, and csscal scale the vector x of
     length n and increment incx by the	constant a.

     For dscal,	sscal, zscal and cscal the constant a is of the	same type as
     the vector	x.  zdscal and csscal scale a "complex"	vector by "real"
     constant.
