Classes
class	EvaluationValues
	Evaluation points of encoding polynomial and symbol values. Following the format of Reliability and Multiplicity matrices: More...
class	ProbabilityCodeword
	Probability score weighted codeword. More...
class	FinalEvaluation
class	GSKV_Interpolation
class	MultiplicityMatrix_SparseOrdering
	Ordering of elements in the sparse matrix according to the column first order. Indexes are pairs of (row, column) indexes. More...
class	MultiplicityMatrix
	Multiplicity matrix corresponding to a reliability matrix. It is implemented as a map representing a sparse matrix where elements are indexed by their (row, column) numbers pair. Once constructed it is normally only used to be traversed column first during the Interpolation algorithm. The ordering of indexes reflects the column first order. More...
class	ReliabilityMatrix
	Reliability Matrix class. Analog data is entered first then the normalization method is called to get the actual reliability data (probabilities). More...
class	RR_Node
	Node in the Roth-Ruckenstein's algorithm. More...
class	RR_Factorization
	Roth-Ruckenstein's factorization. More...
class	RS_Encoding
	Does the Reed-Solomon encoding of a message. his is the genuine, straightforward, non-systematic encoding that takes message symbols to build the successive coefficients of the encoding polynomial. Then this polynomial is evaluated at the evaluation points to make the codeword. More...
class	RSSoft_Exception
	Generic exception class for Reed-Solomon Soft decision decoding library. More...
