# Matlab package: graphical calculus for quantum operations (esp. linear optics)

I need a matlab package that will make my life easier. I have quantum circuits with optical beam splitters, polarizing beam splitters and photodetectors. These circuits are getting very complicated and I am wondering if anyone knows of a matlab package that would make my life easier. A graphical package would be excellent and I suppose any software will do.

Beyond the [qotoolbox](http://qwiki.stanford.edu/index.php/Quantum_Optics_Toolbox), which is showing its age but still very useful, I'm not sure what to suggest. A graphical package does not exist (as far as I'm aware), and is not likely to unless you make it yourself since this not in high demand.

@PiotrMigdal: Done. Bit sad to have such a negative answer, but you are right that it is one.

Sze Tan did not believe in function prototypes when coding in C. It works, just don't go poking around in the source code.
