DESCRIPTION
     Each of these functions performs an in-place  multiplication
     of a matrix by a scalar and then adds an offset.


     For real data, the following equation is used:

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



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

PARAMETERS
     Each of the functions takes the following arguments:

     xz    Pointer to the source and destination matrix.


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


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


     m     Number of rows in the matrix.


     n     Number of columns in the matrix.


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