In English, "pattern recognition" has to do with images. You probably
mean "pattern matching" which is available, as Ray says in tellsimp,
defmatch, etc. There is also a lisp program that does special matching
inside the indefinite integration program, and maybe also in power
series expansion, called M1, probably in the file sin.lisp or sinint.lisp.
