EditDistance

EditDistance[u,v]

gives the edit or Levenshtein distance between strings, vectors or biomolecular sequences u and v.

Details and Options

  • EditDistance[u,v] gives the number of one-element deletions, insertions, and substitutions required to transform u to v.
  • For strings, setting the option IgnoreCase->True makes EditDistance treat lower‐ and upper‐case letters as equivalent.
