Class for storing H or G matrix.
This class stores a matrix variable, specifically either a:
1) Generator matrix, G, in the standard format G = [I P], where I is an identity matrix and P is the parity submatrix.
or
2) Parity matrix, H, in the standard format H = [P' I], where P' is the transpose of the parity submatrix and I is an identity matrix.
This variable can used by the ldpc_gen_mtrx_encoder and ldpc_bit_flip_decoder classes.
