<hr/><a name="_details"></a><h2>Detailed Description</h2>
<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>input: stream of unsigned char; output: stream of float. </p>
<p>out[n D + k] = symbol_table[in[n] D + k], k=0,1,...,D-1</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>
