[ublas] Bindings Problems with Vectors and Matrices

Hello, everyone. This is my first time here, so apologies if I provide
[too much|not enough|the wrong set of] information--or if this isn't the
right place.

I'm trying to get the boost-sandbox BLAS and LAPACK bindings to work,
specifically so I can use syev().

I was getting the same error as another poster (found on Google) with
size_M and size1 in matrices. I corrected that by simply changing the
call from one to the other.

Now I'm getting a similar error in vector_traits.hpp:

$

Note especially that I'm using matrix<double, column_major>, and it's
trying to get &v[0] when v is actually such a matrix.

Is there some easy work-around, or a downgrade that will work for me?

Thanks in advance.

Cheers,
