Function Documentation

void lcode_encode	(	gsl_vector *	codeword,
		gsl_vector *	message,
		gsl_matrix *	G,
		uint32_t	nrows,
		uint32_t	ncols
	)

Encode NROWS bit message X into NCOLS bite codeword C using the NROWS x NCOLS generator matrix G as:

C[1 x NCOLS] = X[1 x NROWS] G[NROWS x NCOLS]

void lcode_matrix_double_to_boolean	(	gsl_matrix *	A,
		uint32_t	nrows,
		uint32_t	ncols
	)

Convert matrix of double-s to matrix of Booleans: if an element x is non-zero => set it to (x mod 2); else leave it to zero

void lcode_vector_double_to_boolean	(	gsl_vector *	vec,
		uint32_t	vec_len
	)

Convert vector of double-s to vector of Booleans: if an element x is non-zero => set it to (x mod 2); else leave it to zero

bool sort_comp_diff_3d_hw_custom	(	differential_3d_t	a,
		differential_3d_t	b
	)

Compare differential_3d_t structs for use with std::sort
