C SYNOPSIS
     void dscal( n, a, x, incx )
     Integer           incx, n;
     double            a;
     double            (*x)[ n ];

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

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