TA Pattern Code

First post, so go easy on me. Really awesome forum!

Tried searching, not much luck. Any good suggestions on open or commercially available source code for patterns (head and shoulders, wedge, double bottoms, etc)? Everything seems prepackaged and hidden. Mostly looking for C++ or Matlab. Or a couple of good books that focus more on the math or programming of patterns? Or anywhere I could use existing code to convert to C++? Information seems scarce, probably for a reason.

Thanks in advance.

Good question. I am also interested for such source code, so if you find it somewhere please send me a link.
