Pattern Matching is an actively used design pattern created in 1960. In computer science, pattern matching is the act of checking a given sequence of tokens for the presence of the constituents of some pattern. In contrast to pattern recognition, the match usually has to be exact: "either it will or will not be a match." The patterns generally have the form of either sequences or tree structures. Uses of pattern matching include outputting the locations (if any) of a pattern within a token sequence, to output some component of the matched pattern, and to substitute the matching pattern with some other token sequence (i.e., search and replace).

  • Pattern Matching ranks in the top 50% of entities I track
  • the Pattern Matching wikipedia page
  • Pattern Matching first appeared in 1960
  • I have 17 facts about Pattern Matching. what would you like to know? email me and let me know how I can help.

Languages with Pattern Matching include haskell, hope, npl-lang

Example from haskell:

fib 0 = 1
fib 1 = 1
fib n | n >= 2
      = fib (n-1) + fib (n-2)
