2013-10-18 Thread Phil Steitz
The decomposition solvers can "invert" non-square matrices. There is no documentation describing what exactly is being returned in these cases. It is not obvious to me exactly what conditions the returned value satisfies in each case when the actual parameter is not square. Do all of them return
