I set up a linux machine without BLAS, LAPACK, ATLAS, hoping that lapacklite would take over. For the moment, I am not concerned about speed -- I just want something that will work with small matricies. I installed numpy, and it passes all of the tests OK, but it hangs when doing eig: u, v = linalg.eig(rand(10,10)) # ....lots of nothing.... Do you need the linear algebra libraries for eig? BTW, inverse seems to work fine.
It should work. Can you give us a specific matrix where it fails? What platform are you running on?
Lapack_lite probably doesn't get much testing from the developers, because we probably all have optimized versions of blas and lapack.
