This is an automated email from the git hooks/post-receive script.
jcorgan pushed a commit to branch master
in repository gnuradio.
commit 62fb423cc415f658e6a7e1b8cafd37d066573a70
Author: Tom Rondeau <address@hidden>
Date: Mon Oct 12 16:42:49 2015 -0400
fec: LDPC: reworking code to make sure API is ok.
Reintroduced original ldpc_encoder for compatibility. Renamed new
version to ldpc_par_mtrx_encoder.
