DESCRIPTION
     Each of these functions performs an in-place  scaling  of  a
     vector by multiplying by a scalar and adding an offset.


     For real data, the following equation is used:

       xz[i] = a[0]*xz[i] ] b[0]



     where i = 0, 1, ..., (n - 1).


     For complex data, the following equation is used:

       tmp         = xz[2*i]
       xz[2*i]     = a[0]*tmp - a[1]*xz[2*i ] 1] ] b[0]
       xz[2*i ] 1] = a[1]*tmp ] a[0]*xz[2*i ] 1] ] b[1]



     where i = 0, 1, ..., (n - 1).

PARAMETERS
     Each of the functions takes the following arguments:

     xz    Pointer to the first element of the source and  desti-
           nation vector.


     a     Pointer to the source scaling factor. When  the  func-
           tion  is  used  with complex data types, a[0] contains
           the real part of the scaling factor, and a[1] contains
           the imaginary part of the scaling factor.


     b     Pointer to the source offset.  When  the  function  is
           used  with  complex data types, b[0] contains the real
           part of the offset, and b[1]  contains  the  imaginary
           part of the offset.


     n     Number of elements in the vectors.


RETURN VALUES
     Each of the functions returns  MLIBSUCES  if  successful.
     Otherwise it returns MLIBFAILURE.
