Re: [ublas] Adding LAPACK bindings to boost

Dear Jeremy,

Such issues are usually discussed in the ublas mailing list (See CC). I 
have not followed the latest discussion on the evolution of lapack 
bindings. Some functions have been added recently. I do not recall 
discussions on the functions you want to use. Someone can confirm this?

Maybe we should change the phrase "on request" in the paper. Since this 
is an open source project and contributions from the community are 
highly appreciated. I would encourage you to have a look at e.g. gesv() 
and getrf() bindings and see whether you are able to write bindings (I 
warn you: it is technical). Otherwise I will try and find some time end 
of June.

Best regards,

Karl
