Detailed Description

Base class for FEC matrix objects.

Base class of ldpc_H_matrix and ldpc_G_matrix classes. The child objects can be either generator matrices or parity check matrices. This base class can be provided to the decoder ldpc_bit_flip_decoder, whereas the encoder classes ldpc_gen_mtrx_encoder and ldpc_encoder will not accept this base class; they require one of the child classes.
