<div class="refsection"><h3 class="title">Description</h3>
<p class="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.</p></div>
