uBLAS "official link" to LAPACK is made through ATLAS. However, for Windows users, it is quite difficult to use ATLAS due to overly complex compilation ...
uLAPACK would be nice but impractical I would guess. LAPACK shouldn't require ATLAS but will require BLAS from somewhere. The alternative is to either makes a...

Hi Peter, I think you have misunderstood my point: I just want to have a wrapper around (C)Lapack methods that is compatible with uBLAS. I do not want at all...

... True. Those in `amos', `blas' and `traits' directories were written by Toon, and those in `atlas' and `lapack' by Joerg (Joerg sent them to me when he...
