As I mentioned in previous emails, there isn't a feasible general solution for LAPACK with the column-major matrix restriction, due to the combinatorial explosion of cases that must be handled. We could adopt FLAME, which is a much more general framework, C-based and faster than LAPACK. I really think this is a better way to go than LAPACK. Unfortunately it doesn't have so many routines at the moment. -- Brian Gough
