 * \details
 * The output stream contains shorts with twice as many output
 * items as input items. For every complex input item, we produce
 * two output shorts that contain the real part and imaginary part
 * converted to shorts:
 *
 * \li output[0][n] = static_cast<short>(input[0][m].real());
 * \li output[0][n+1] = static_cast<short>(input[0][m].imag());
