%disp( code ) will also print the large H matrices in Octave, making it useless
%Octave workaround:

N   = code.N
K   = code.K
M   = code.M
Z   = code.z
Nb  = code.Nb
Mb  = code.Mb
R   = code.Rc
Hbm = code.Hbm ;
Hs  = code.Hs ;
H   = code.H ;


%get default encoder and decoder parameters
enc = QCLDPCEncode()
dec = QCLDPCDecode()

enc.method  = 'bitmap' %switch to 'bitmap' encoder from default 'array'

dec.method  = 'fixed' %switch to fixed-point implementation
dec.nthread = 32      %switch to multithreaded decoder implementation

%recalculate dependent parameters:
enc = QCLDPCEncode( enc )
dec = QCLDPCDecode( dec )

%saves ldpc.h and ldpc.c
