I hesitate to rate this because it was written for MATLAB 5.2, but it needs plenty of revision to work on 7.11. I found uses of "break" where "return" (or better, error statements) are needed; and the mysterious command "floppy". I was not strongly motivated to get the solver working, so I don't know how many other problems there are.
