Although it is far from perfect, there are around 600 pages of
documentation in the Octave manual, and the .* operator does appear in
the index...

You can write

  function result = f (t, t0)
    if (t < t0)
      result = a (t);
    elseif (t == t0)
      result = b (t);
    else
      result = c (t);
    endif
  endfunction

Here I'm assuming T and T0 are scalars and A, B, and C are other
functions.  If you meant something else, then state it more precisely
and maybe someone can help you.
