Hamming distance of strings
WebIn a more general context, the Hamming distance is one of several string metricsfor measuring the edit distancebetween two sequences. It is named after the American mathematician Richard Hamming. A major application is in coding theory, more specifically to block codes, in which the equal-length strings are vectorsover a finite field. WebThe Hamming distance between two vectors is the number mismatches between corresponding entries. In case of the Hamming distance the two strings must have the same length. In case of the Levenshtein (edit) distance a scoring and a trace-back matrix are computed and are saved as attributes "ScoringMatrix" and "TraceBackMatrix" .
