DESCRIPTION
     Each of these functions performs an  in-place  averaging  of
     two matrices.


     It uses the following equation:

       xz[i] = (xz[i] + y[i] + 1) / 2

     where i = 0, 1, ..., (m*n - 1) for real data; i = 0, 1, ...,
     (m*n*2 - 1) for complex data.

PARAMETERS
     Each of the functions takes the following arguments:

     xz    Pointer to the first source and destination matrix.


     y     Pointer to the second source matrix.


     m     Number of rows in the matrices.


     n     Number of columns in the matrices.


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