DESCRIPTION
     Each of these functions performs a multiplication of a  vec-
     tor by a scalar and shifts the result.


     For real data, the following equation is used:

       z[i] = x[i] * c[0] * 2**(-shift)



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


     For complex data, the following equation is used:

       z[2*i]     = (x[2*i]*c[0] - x[2*i + 1]*c[1]) * 2**(-shift)
       z[2*i + 1] = (x[2*i]*c[1] + x[2*i + 1]*c[0]) * 2**(-shift)



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

PARAMETERS
     Each of the functions takes the following arguments:

     z        Pointer to the first element of the result vector.


     x        Pointer to the first element of the source vector.


     c        Pointer to the source scalar. When the function  is
              used  with  complex  data  types, c[0] contains the
              real part of the scalar, and c[1] contains the ima-
              ginary part of the scalar.


     n        Number of elements in each vector.


     shift    Right shifting factor. The ranges  of  valid  shift
              are:

                1 < shift < 8   for U8, S8, U8C, S8C types
                1 < shift < 16  for S16, S16C types
                1 < shift < 31  for S32, S32C types



RETURN VALUES
     Each of the functions returns  MLIB_SUCCESS  if  successful.
     Otherwise it returns MLIB_FAILURE.
