+   <para>
+This is an Octave function.
+Every complex element of z is expected to have a complex-conjugate elsewhere in z. From the pair of complex-conjugates, the one with the negative imaginary part is removed.
+If the magnitude of the imaginary part of an element is less than the thresh, it is declared as real.
