<div class="textblock"><p>Map a stream of symbol indexes (unpacked bytes or shorts) to stream of float or complex onstellation points.in <code>D</code> dimensions (<code>D</code> = 1 by default)</p>

<p>The combination of gr_packed_to_unpacked_XX followed by gr_chunks_to_symbols_XY handles the general case of mapping from a stream of bytes or shorts into arbitrary float or complex symbols.</p>
