Hi. That was done deliberately, and a similar decision was made
in some other parts of the library. The idea is to make the interfaces
as wide as possible; for instance, if we had only gsl_vector type
interfaces for these functions, then there would people with
the opposite complaint.

If there is enough interest, wrapper functions can be created
with gsl-type interfaces. It's easy to do, but we just didn't
have the time to do that and never got around to it.

Meanwhile, you can use the members for gsl_vector and
gsl_matrix which allow access to the underlying data
representation. Maybe a little annoying, but functionally
the same.

Thanks.
