Hello Jeremy,

The report at
http://www.cs.kuleuven.be/publicaties/rapporten/tw/TW506.abs.html
says
"The BLAS bindings in Boost Sandbox contain interfaces to some BLAS functions. Functions are added on request."
and
"As for the BLAS, the Boost Sandbox does not contain a full set of interfaces to LAPACK routines, but only very commonly used subprograms. On request, more functions are added to the library."
This model will probably only work if explicit requests are made. Can you tell me the names of the LAPACK functions that you need?
Regards,
Thomas

Betreff: [ublas] How to access pointer to matrix/vector elements?
I am trying to call LAPACK functions using ublas objects. The LAPACK
functions require a pointer to the first array element of the matrix. I
tried:
matrix<double> A(3,3);
and then pass A.data() as the pointer to the elements of A. The compiler
didn't like that. What is the best way to get the pointer to the elements
of A?
I know there are some experimental libraries to bind LAPACK and ublas
together. I would like to use these to avoid problems like those mentioned
above. Unfortunately, the LAPACK functions I want to use are not (yet)
implemented into the boostsandbox.
Thanks,
Jeremy
